Subject: block: Minor blk_account_io_start usage cleanup
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a21f2a3ec62abe2e06500d6550659a0ff5624fbb;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

block: Minor blk_account_io_start usage cleanup

blk_account_io_start does not need to be wrapped with blk_do_io_stat
ais it already checks for that condition.
