Here's the problem:
v4l/Makefile writes to KERNELRELEASE and v4l/.version
-e 'printf ("VERSION=%s\nPATCHLEVEL:=%s\nSUBLEVEL:=%s\nKERNELRELEASE:=%s.%s.%s%s\n",' \
-e ' $$version,$$level,$$sublevel,$$version,$$level,$$sublevel,$$extra);' \
$ cat v4l/.version
VERSION=3
PATCHLEVEL:=4
SUBLEVEL:=39
KERNELRELEASE:=3.4.3913
SRCDIR:=/tmp/sandbox/custom-linux-3.4
Then $(MAKE) -C ../linux apply_patches calls
patches_for_kernel.pl 3.4.3913
which computes kernel_version
= 3 << 16 + 4 << 8 + 3913 = 0x031349
which is incorrectly interpreted as kernel 3.19.73
thus the correct patches are not applied.
Trivial patch follows. Will test right away.
Regards.
