[PATCH] usb:musb:musb_host: Handle highmem in PIO mode

2012-08-01 Thread Virupax Sadashivpetimath
In case of USB bulk transfer, when himem page is received, the usb_sg_init function sets the urb transfer buffer to NULL. When such URB transfer is handled, kernel crashes in PIO mode. Handle this by mapping the highmem buffer in PIO mode. Signed-off-by: Virupax Sadashivpetimath --- drivers
