Subject: [media] pwc: Use vb2 queue mutex through a single name
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0ab61196e5b6d73ef5bb058a323d3ac7309cdc62;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[media] pwc: Use vb2 queue mutex through a single name

This lock was being taken using two different names
(pointers) in the same function.
Both names refer to the same lock,
so this wasn't an error; but it looked very strange.
