Series rtlwifi: rtl8192ee: Replace local TX and RX bit manipulation macros | expand

Commit Message

Larry Finger Aug. 31, 2019, 6:06 p.m. UTC 
This driver uses a set of local macros to manipulate the RX and TX
descriptors, which are all little-endian quantities. These macros
are replaced by the bitfield macros le32p_replace_bits() and
le32_get_bits(). In several places, the macros operated on an entire
32-bit word. In these cases, a direct read or replacement is used.
