scsi: fas216: fix sense buffer initialization
[ Upstream commit 96d5eaa9bb74d299508d811d865c2c41b38b0301 ] While testing with the ARM specific memset() macro removed, I ran into a compiler warning that shows an old bug: drivers/scsi/arm/fas216.c: In function 'fas216_rq_sns_done': drivers/scsi/arm/fas216.c:2014:40: error: argument to 'sizeof' in 'memset' call is the same expression as the destination; did you mean to provide an explicit length? [-Werror=sizeof-pointer-memaccess] It turns out that the definition of the scsi_cmd structure changed back in linux-2.6.25, so now we clear only four bytes (sizeof(pointer)) instead of 96 (SCSI_SENSE_BUFFERSIZE). I did not check whether we actually need to initialize the buffer here, but it's clear that if we do it, we should use the correct size.
