Subject: [PATCH 01/16] staging: rtl8723bs: simplify function selecting channel group
Date: Wed, 21 Jul 2021 15:37:08 +0200	[thread overview]
Message-ID: <a5536788004c44fe819c0eab0d19504824af46cd.1626874164.git.fabioaiuto83@gmail.com> (raw)
In-Reply-To: <cover.1626874164.git.fabioaiuto83@gmail.com>

simplify function Hal_GetChnlGroup8723B(). It returns
an unused and unnecessary bool value telling which
band the device works on. Since we work only on
2.4Ghz band and the useful return value is the
second function argument we convert the return type to
void.

remove 5Ghz dead code either (for channel > 14).
