Subject: Re: [PATCH1/2] Trivial patch in efifb.c to solve common indent issue
and indent error
I have created two patch now.
0001-Trival-patch-improved-indentation-in-efifb.c-file.patch:
This patch solves indentation issue in efifb.c file.
This don't has any code change.
I checked with checkpatch.pl it has some warning to remove some old functions in
efifb.c. my changes are not to address that. That changes I can try in my next
patch.
0002-Trivial-patch-In-this-patch-printk-is-replaced-by-pr.patch:
This is addressing following changes:
1- It has removed "quoted string split across lines" warning.
2- There was static initialization of request_mem_succeeded, which is removed.
3- Assignment in if condition, this is fixed.
This one I have checked with checkpatch.pl it don't has any warning or comment.
I am sending these patches with mutt.
