From: Fabio Estevam <feste...@denx.de> The musl issue that 0004-Do-not-use-getsubopt.patch fixes has already been addressed by the following v4l-utils upstream commit:
commit 6e19bb895a16a9a247524ac526ab47f576cc36f6 Author: Hans Verkuil <hverkuil-ci...@xs4all.nl> Date: Thu Nov 25 10:59:22 2021 +0100 v4l-utils: use v4l_getsubopt instead of getsubopt Android doesn't have getsubopt at all, and some libc implementations use a getsubopt variant that behaves slightly different. So add a new v4l-getsubopt.h header that either just uses the glibc function (if glibc is detected) or uses a static inline v4l_getsubopt that is copied from glibc. This should avoid such problems.
