Subject: [PATCH] media: mali-c55: Fix clock leak on reset deassert failure
Date: Tue, 9 Jun 2026 12:37:47 +0100 [thread overview]
Message-ID: <20260609113747.39592-1-devnexen@gmail.com> (raw)
__mali_c55_power_on() enables the clocks before deasserting the resets,
but bails out on a deassert failure without disabling them again. Both
callers treat a failed power-on as already cleaned up, so the clocks are
left enabled.
Disable them on the error path.
Fixes: d5f281f3dd29 ("media: mali-c55: Add Mali-C55 ISP driver")
