Subject: [media] s5p-mfc: Fix unbalanced call to clock management
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a5cb00eb4223458250b55daf03ac7ea5f424d601;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[media] s5p-mfc: Fix unbalanced call to clock management

Clock should be turned off after calling s5p_mfc_init_hw() from the
watchdog worker, like it is already done in the s5p_mfc_open() which also
calls this function.
