a) fixes a lockup due to a missing restart.

generally the pdata needs to be a constant pointer in the device
state structure. This patch makes the pdata as a constant pointer
and alongside returns -EINVAL when pdata is NULL.

the ths7303_setup() was doing the same thing as ths7303_setval()
except that ths7303_setval() sets it to some particular mode.
This patch removes ths7303_setup() function and calls ths7303_setval()
in the probe setting the device to 480I_576I filter mode in the probe.

This patch removes init_enable option from pdata, the init_enable
was intended that the device should start streaming video immediately
but ideally the bridge drivers should call s_stream explicitly for such
devices to start video.

Trivial cleanup of the driver.
Changes for v2:
1: Dropped the asynchronous probing and, OF
support patches will be handling them independently because of dependencies.
2: Arranged the patches logically so that git bisect
succeeds.

Hi Sarah and Alan,
Thanks for the comments. I will make the following revisions:
1. Call pm_runtime_get_noresume only when the first device is
connected, and call pm_runtime_put when the last device is
disconnected.
2. Wrap the calls in an ifdef CONFIG_USB_DEFAULT_PERSIST.
3. Make sure that all

Not checking dma_mapping_error on these dma_map_single uses keeps
