<content type='text'>
commit 9063f1f15eec35e5fd608879cef8be5728f2d12a upstream.

Call input_set_abs_params instead of manually setting absbit only.
This fixes this oops:

The usb regulator supplies (usb1v5, usb1v8 &amp; usb3v1) must be available
before adding the twl4030_usb child, else twl4030_usb_ldo_init() will
always fail thus causing boot lock-up.

This patch fixes boot on OMAP systems using the twl4030 usb transceiver.

After m68k's task_thread_info() doesn't refer to current,
it's possible to remove sched.h from interrupt.h and not break m68k!
Many thanks to Heiko Carstens for allowing this.

The I2C_CLIENT_INSMOD_1 macro is only useful for i2c drivers which
implement device detection. The ab3100 driver doesn't, so there is no
point in calling it.
