Subject: [PATCH] media: amphion: Remove unused functions
From: "Dr. David Alan Gilbert" <linux@...blig.org>
The functions:
vpu_color_get_default()
vpu_color_check_full_range()
vpu_color_check_primaries()
vpu_color_check_transfers()
vpu_color_check_matrix()
have been unused since 2022's
commit 1925665ef403 ("media: amphion: remove redundant check of
colorspace in venc_s_fmt")
The (empty) function vpu_mbox_enable_rx() has been unused since it
was added in 2022 by the
commit 61cbf1c1fa6d ("media: amphion: implement vpu core communication
based on mailbox")
Remove them.
Signed-off-by: Dr. David Alan Gilbert <linux@...blig.org>
