Subject: [PATCH 4/7] media: mediatek: vcodec: simplify cleanup using __free
Date: Wed, 11 Mar 2026 01:35:10 +0530	[thread overview]
Message-ID: <20260310200513.2162018-5-sanjayembedded@gmail.com> (raw)
In-Reply-To: <20260310200513.2162018-1-sanjayembedded@gmail.com>

From: Sanjay Chitroda <sanjayembeddedse@gmail•com>

Replace manual cleanup logic with __free attribute from cleanup.h. This
removes explicit kfree() calls and simplifies the error handling paths.

No functional change intended for kmalloc().
