Because Grant didn't want me doing udelay(50) just to delay things in order to give the AC97 controller time to initialize. Your function lets me loop on cpu_relax() for 50us. I have to delay 50us because ALSA tries to access the hardware immediately after the function returns. > > -- > Timur Tabi > Linux kernel developer at Freescale > -- Jon Smirl jonsm...@gmail.com _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
