| Subject: media: tc358743: Fix error return code in tc358743_probe_of() |
| |
| From: Zhen Lei <thunder.leizhen@huawei.com> |
| |
| [ 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. |
