Subject: thermal: clock_cooling: Fix missing mutex_init()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=165989a5b667b90589f21c8affe496ad21f08591;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

thermal: clock_cooling: Fix missing mutex_init()

The driver allocates the mutex but not initialize it.
Use mutex_init() on it to initialize it correctly.

This is detected by Coccinelle semantic patch.
