Subject: scsi: pmcraid: remove redundant check to see if request_size is less than zero
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b77b36cb7272ec5b9fb000e2ff18e947d9586a22;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

scsi: pmcraid: remove redundant check to see if request_size is less than zero

The 2nd check to see if request_size is less than zero is redundant
because the first check takes error exit path on this condition. So,
since it is redundant, remove it.
