Subject: [SCSI] sg: remove unnecessary indentation
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=dddbf8d908e89afb14a49502f568d2a2b814436d;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

[SCSI] sg: remove unnecessary indentation

blocking is de-facto a constant and the now-removed comment wasn't all
that useful either.  Without them and the resulting indentation the code
is a bit nicer to read.
