Subject: [PATCH 5.15 378/917] media: meson-ge2d: Fix rotation parameter changes detection in ge2d_s_ctrl()

From: Christophe JAILLET <christophe.jaillet@...adoo.fr>

[ Upstream commit 4b9e3e8af4b336eefca1f1ee535bc4b6734ed6aa ]

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'.

Instead of fixing the test, just remove it and copy 'fmt' unconditionally.
