Subject: [PATCH] dmaengine: mv_xor_v2: Fix a resource leak in mv_xor_v2_remove()
Git-commit: 081195d17a0c4c636da2b869bd5809d42e8cbb13
Patch-mainline: v6.1-rc5
References: git-fixes
A clk_prepare_enable() call in the probe is not balanced by a corresponding
clk_disable_unprepare() in the remove function.
Add the missing call.
Fixes: 3cd2c313f1d6 ("dmaengine: mv_xor_v2: Fix clock resource by adding a register clock")
