[RFC PATCH 15/41] staging: dwc2: re-use hptxfsiz variable

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

 



For some reason, the value of the HPTXFSIZ register was built in the
ptxfsiz variable, while there was also a hptxfsiz variable availble.
Better just use that.
