[PATCH 3/4] staging: r8188eu: remove NumTotalRFPath from struct hal_data_8188e

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

 



NumTotalRFPath is 1 in this driver and it is only used as exit condition
in for loops. Since NumTotalRFPath is always 1, all the loops have only a
single iteration. So we can remove the for loops and the NumTotalRFPath
variable.
