**RESENT THE PATCH BECAUSE I MESSED UP THE EMAIL ADDRESS FOR LKML IN THE
PREVIOUS MAIL. SORRY.**
This patch series tries to fix the following warnings by checkpatch.pl
in core/rtw_wlan_util.c:

I wanted to ask for comments on the names of these functions and if such
a patch series would be acceptable.
The first patch refactors the code by introducing two new functions
sort_wmm_ac_params and get_realtek_assoc_AP_vender.
The second patch removes unnecessary braces from the conditional
statements in check_assoc_AP function.

2.31.1
Reduce the number of indents in rtw_wlan_util.c file by refactoring the
code.
Moved the part of code that rearranged ac paramaters in the function
WMMOnAssocResp to a separate function named sort_wmm_ac_params. It takes
both the array of ac params and their indexes as arguments and sorts them.
Has return type void.
Moved the part of code that checked for the realtek vendor in the
function check_assoc_AP to a separate function named
get_realtek_assoc_AP_vender. It takes a pointer to struct
ndis_80211_var_ie as an argument and returns a u32 realtek vendor.

2.31.1
Removed the braces from if else statements in core/rtw_wlan_util.c since
the previous commit 6a257dd6de516573 caused all conditional blocks to
have a single statement in the function check_assoc_AP.

Why is [RFC] in the subject line? Do you not want these merged?

No, since I wanted to ask about the names of these functions I sent
these patches as RFC. If these names are fine, I'll send another patch
series with a couple of patches besides these that fix other much simpler
coding style issues in the same file.

I hope this clears the confusion caused.
