media: tc358743: Fix error return code in tc358743_probe_of()
[ 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.
