Subject: [PATCH v3 media-next] media: rkisp1: Fix unused value issue
Date: Tue, 19 Nov 2024 11:32:20 +0530	[thread overview]
Message-ID: <20241119060220.70124-1-dheeraj.linuxdev@gmail.com> (raw)

This commit fixes an unused value issue detected by Coverity (CID
1519008). The error condition for the invalid MIPI CSI-2 is not
properly handled as the break statement would only exit the switch block
and not the entire loop. Fixed this by returning the error immediately
after the switch block.

Fixes: 7d4f126fde89 ("media: rkisp1: Make the internal CSI-2 receiver
optional")
