Thanks, at last :-).
Is there any tree through which it can reach torvalds?
Thanks,

The way I would have found this information about any driver is by looking at its git-log and check via which path patches have been going till date. Maintainers normally adds there signed-off's to patches that go through them. Andrew Morton, is the one who applied rtc-spear patches till now. Added in cc. -- viresh

the config was freed and its used again at rtc_device_unregister which leads to a kernel panic. so, do it right after the rtc_device_unregister Signed-off-by: Devendra Naga <devendra.aaru@gmail.com> --- drivers/rtc/rtc-spear.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
