USB: OTG: Use work_queue in set_vbus for TWL6030 transciever
With this commit: cccad6d4b103e53fb3d1fc1467f654ecb572d047
usb: otg: notifier: switch to atomic notifier
Following dumps are observed on attach/detach for MUSB HOST
mode and on a detach for MUSB Device mode.
BUG: sleeping function called from invalid context at kernel/mutex.c:85
where, the source is:
twl6030_usb_irq
->atomic_notifier_call_chain
->musb_otg_notifications
->twl6030_set_vbus
->twl_i2c_write_u8
->mutex_lock
This patch moves the i2c writes in set_vbus function to a
work-queue thereby avoiding I2C writes in atomic context.
Tested HOST and Device mode functionality on OMAP4460
