iwlegacy: Silence DEBUG_STRICT_USER_COPY_CHECKS=y warning
Enabling DEBUG_STRICT_USER_COPY_CHECKS causes the following
warning:
In file included from arch/x86/include/asm/uaccess.h:573,
from include/net/checksum.h:25,
from include/linux/skbuff.h:28,
from drivers/net/wireless/iwlegacy/iwl-4965-rs.c:28:
In function 'copy_from_user',
inlined from 'iwl4965_rs_sta_dbgfs_scale_table_write' at
drivers/net/wireless/iwlegacy/iwl-4965-rs.c:2616:
arch/x86/include/asm/uaccess_64.h:65:
warning: call to 'copy_from_user_overflow' declared with
attribute warning: copy_from_user() buffer size is not provably
correct
presumably due to buf_size being signed causing GCC to fail to
see that buf_size can't become negative.
