drivers/net/eql.c: prevent reading uninitialized stack memory
commit 44467187dc22fdd33a1a06ea0ba86ce20be3fe3c upstream.
Fixed formatting (tabs and line breaks).
The EQL_GETMASTRCFG device ioctl allows unprivileged users to read 16
bytes of uninitialized stack memory, because the "master_name" member of
the master_config_t struct declared on the stack in eql_g_master_cfg()
is not altered or zeroed before being copied back to the user. This
patch takes care of it.
