Subject: [PATCH] media: meson-ge2d: Fix rotation parameter changes detection in 'ge2d_s_ctrl()'
Date: Thu, 29 Jul 2021 21:49:25 +0200	[thread overview]
Message-ID: <6cb8efcadcf8c856efb32b7692fc9bf3241e3bc3.1627588010.git.christophe.jaillet@wanadoo.fr> (raw)

There is likely a typo here. To be consistent, we should compare
'fmt.height' with 'ctx->out.pix_fmt.height', not 'ctx->out.pix_fmt.width'.

Fixes: 59a635327ca7 ("media: meson: Add M2M driver for the Amlogic GE2D Accelerator Unit")
Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr>

I've not looked deeply in the code, but why is this test needed in the
first place?
Couldn't we assigned 'ctx->out.pix_fmt = fmt' un-conditionally?
