Subject: [PATCH v2] media: meson-ge2d: Fix rotation parameter changes detection in 'ge2d_s_ctrl()'

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.

v2: axe the tests. The structure is small, and it is likely that it was
    already copied with the broken test.
