rtlwifi: rtl88188ee: Replace local bit manipulation macros
Browse files Browse the repository at this point in the history 
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.
