stable inclusion from stable-v6.6.2 commit 61fb93fb91ca7cd4b4655ec866bf1f9a13dbfeff category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8IW7G
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit a9a3f54a23d844971c274f352500dddeadb4412c ]
The return code of regmap_multi_reg_write() call related to "MDSYNC down" sequence is shadowed by the subsequent wait_for_completion_timeout() invocation, which is expected to time timeout in case the write operation failed.
Let cs35l41_global_enable() return the correct error code instead of -ETIMEDOUT.
