Subject: [PATCH next] media: ti: j721e-csi2rx: Fix NULL vs IS_ERR() bug in ti_csi2rx_request_max_ppc()
Date: Wed, 27 Aug 2025 16:02:57 +0300	[thread overview]
Message-ID: <aK8CATf4EdcYcTe-@stanley.mountain> (raw)

The media_entity_remote_source_pad_unique() function never returns NULL,
it returns error pointers.  Change this check from a NULL check to an
IS_ERR() check.

Fixes: 31f91c5224cd ("media: ti: j721e-csi2rx: Support multiple pixels per clock")
