2013-01-20staging: line6: clean up line6_pod_process_message()Stefan Hajnoczi1-77/+19
Previous versions of the line6 driver snooped MIDI traffic in order to make device state accessible via sysfs attributes. This involved a lot of logic in line6_pod_process_message() that has since been removed. Drop unused conditionals in line6_pod_process_message() and reduce the levels of indentation. Only two MIDI messages are still tracked: the POD version message on startup and monitor level changes originating from the device.

2012-11-26staging: line6: drop dump requests from pod startupStefan Hajnoczi1-40/+4
The pod startup procedure dumps model data. This is no longer useful since the sysfs attrs which expose this information to userspace have been removed.

2012-11-26staging: line6: drop pod prog_data buffersStefan Hajnoczi1-43/+3
The driver no longer keeps state of MIDI-accessible device parameters. Drop the buffers but be careful to keep the device startup procedure working even though we no longer store the contents of the dump request. The startup procedure will be simplified in a later patch. Signed-off-by: Stefan Hajnoczi <stefanha@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-11-26staging: line6: drop MIDI parameter sysfs attrsStefan Hajnoczi1-9/+0
Both pod.c and variax.c expose the device's MIDI parameters as sysfs attrs. Knowledge of MIDI constants should be in userspace, not in the driver. Drop the sysfs attrs and let userspace interpret parameters it cares about instead. Signed-off-by: Stefan Hajnoczi <stefanha@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-11-26staging: line6: drop amp/effects dump request triggersStefan Hajnoczi1-9/+0

2012-11-26staging: line6: drop tuner param filteringStefan Hajnoczi1-21/+0

2012-11-26staging: line6: drop pod.c raw sysfs attrStefan Hajnoczi1-13/+0
The raw sysfs attr transmits MIDI messages with less filtering. This was a useful debugging tool while the staging driver still had a lot of state and filtering. It is not useful anymore since the filtering is being dropped. Signed-off-by: Stefan Hajnoczi <stefanha@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-11-26staging: line6: drop midi_postprocess flagStefan Hajnoczi1-34/+0
It is no longer necessary to trigger on MIDI transmit messages that will change the state of the device since: 1. We've dropped the midi_postprocess sysfs attr in a previous commit so it is not possible to activate this feature anymore. 2. The other sysfs attrs that could inspect the state after a dump request have been dropped. Therefore we can safely remove this dead code.

2012-11-26staging: line6: drop tuner_pitch sysfs attrStefan Hajnoczi1-101/+1
Dropping this final tuner sysfs attr also leaves the POD_GET_SYSTEM_PARAM() macro, pod_get_system_param_string(), and pod_get_system_param_int() unused. Remove them immediately to avoid compiler warnings. POD_monitor_level is now the only SYSEX value that needs to be watched by the driver since the ALSA volume control should reflect the current monitor volume level used by the device. Therefore, drop the switch statement entirely and just check for POD_monitor_level, ignoring unknown system parameter changes.

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo1-0/+2
implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.
