Subject: [media] c8sectpfe: Combine three checks into a single if block
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1ea7252d978637dca24f89c72dee887fe2bef689;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[media] c8sectpfe: Combine three checks into a single if block

The variable "tsin" was checked three times in a loop iteration of the
c8sectpfe_tuner_unregister_frontend() function.
This implementation detail could be improved by the combination of the
involved statements into a single if block so that this variable will be
checked only once there.
