Subject: Re: [PATCH 3/7] staging: r8188eu: remove GetPSDData()
Thus wrote Michael Straube (straube.linux@...il.com):
> Function GetPSDData() is not used, remove it. It is the only user of
> ConvertTo_dB() and ODM_StallExecution(), remove these two functions
> and the now unused dB_Invert_Table as well.
