[ALSA] Remove redundant NULL checks before kfree
Timer Midlevel,ALSA sequencer,ALSA<-OSS sequencer,Digigram VX core I2C tea6330t,GUS Library,VIA82xx driver,VIA82xx-modem driver CA0106 driver,CS46xx driver,EMU10K1/EMU10K2 driver,YMFPCI driver Digigram VX Pocket driver,Common EMU synth,USB generic driver,USB USX2Y Checking a pointer for NULL before calling kfree() on it is redundant, kfree() deals with NULL pointers just fine. This patch removes such checks from sound/ This patch also makes another, but closely related, change. It avoids casting pointers about to be kfree()'ed.
