Subject: [PATCH 1/1] wireless: in _rtl92c_phy_calculate_bit_shift remove comparing bitmask against 1

From: "Devendra.Naga" <[email protected]>

in _rtl92c_phy_calculate_bit_shift everytime the right shifted bitmask
is AND with 1 and compared against 1. i.e.
if ((bitmask >> i) & 0x1 == 1)
break;
which in the if condition is anyway becomes a 1 or 0.

Once again, the patch is OK, but the subject is not good.
