[PATCH v3 0/4] staging: rtl8723bs: Style clean-up in rtw_mlme.c

[Wambui Karuga]

This patchset addresses multiple style and formatting issues reported by
checkpatch.pl in drivers/staging/rtl8723bs/core/rtw_mlme.c

PATCH v2 of the series corrects the "patchest" mispelling in the
original cover letter and provides a clearer subject line.

PATCH v3 of the series incorporates newer changes in rtw_mlme.c
on staging-testing.

Wambui Karuga (4):
  staging: rtl8723bs: Remove comparisons to NULL in conditionals
  staging: rtl8723bs: Remove unnecessary braces for single statements
  staging: rtl8723bs: Remove comparisons to booleans in conditionals.
  staging: rtl8723bs: Remove unnecessary blank lines

This new cast is unnecessary and weird.

Ah, I missed that, good catch.  I'll go drop this patch now.

Wambui, please fix up and resend.

And that caused the second patch to get dropped as well.  I'll just drop
them all, can you redo the whole series please?

The cast seems to have been removed earlier by Nachammai Karuppiah and
added to staging-testing, but I added it back when I cherry-picked my changes to the new
file. 

Sorry. :(
I can remove the cast and send a new series.
Thanks.
