X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=eb3ed2af54b0a93a8af42f22d4a95d80fa2cea72;p=buildroot.git

package/strace: fix build with v5.2 kernel headers

Add upstream patch with a workaround to incompatible change in kernel
headers.

Regenerate the v4l2_pix_fmts.h header which is pre-generated from
v4l2_pix_fmts.in in the strace tarball.

Fixes:
