Subject: cfq-iosched: Adjust one function call together with a variable assignment
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1cf417530375b475d4a8a9f18dc0867f91e52d78;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

cfq-iosched: Adjust one function call together with a variable assignment

The script "checkpatch.pl" pointed information out like the following.

ERROR: do not use assignment in if condition

Thus fix the affected source code place.
