Do not even bother fixing theoretical issues if you're going to be introducing a _REAL_ serious regression into the code with your "fix": drivers/net/usb/smsc95xx.c: In function ‘smsc95xx_resume’: drivers/net/usb/smsc95xx.c:1674:5: warning: ‘pdata’ is used uninitialized in this function [-Wuninitialized] u8 suspend_flags = pdata->suspend_flags; ^ So, instead of a theoretical issue, we now have a real guaranteed crash. You did not compile test this change, and you definitely did not functionally test this change either. Please do not do this ever again, thanks.
