[PATCH v2 01/21] staging: wilc1000: replace crc7_byte() with inline macro CRC7_BYTE

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Replace the function call for crc7_byte() with macro CRC7_BYTE.
crc7_byte() was called in close while(), so replaced it with macro to
avoid extra functional call depth.
