Subject: [PATCH 0/3] driver core: add probe error check helper
Hi Greg, Rafael,
This patchset proposes probe helper function which should simplify little bit
resource acquisition error handling, it also extend it with adding defer probe
reason to devices_deferred property:
# cat /sys/kernel/debug/devices_deferred
exynos-hdmi 13970000.hdmi: cannot find out bridge
arizona-extcon
tm2-audio sound: Unable to get codec_dai_name
The last patch was generated by cocci script to show the gain for the most
obvious probe_err usage scenarios. Of course there are many more places where it
could be used.
If the 1st patch will be accepted I can split 3rd one per subsystems if neccessary.
Regards
Andrzej
