From: Zhen Lei <thunder.leizhen@huawei.com> stable inclusion from stable-5.10.50 commit 0109910cbdd850e3b9416e7ae04a6859579df86e bugzilla: 174522 https://gitee.com/openeuler/kernel/issues/I4DNFY Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit a6b1e7093f0a099571fc8836ab4a589633f956a8 ] When the CSI bps per lane is not in the valid range, an appropriate error code -EINVAL should be returned. However, we currently do not explicitly assign this error code to 'ret'. As a result, 0 was incorrectly returned.
