Subject: [PATCH AUTOSEL 5.4 30/31] wifi: rtlwifi: rtl8723{be,ae}: using calculate_bit_shift()
From: Su Hui <suhui@...china.com>
[ Upstream commit 5c16618bc06a41ad68fd8499a21d35ef57ca06c2 ]
Using calculate_bit_shift() to replace rtl8723_phy_calculate_bit_shift().
And fix an undefined bitwise shift behavior problem.
