2013-04-14[media] soc-camera: fix typos in the default format-conversion tableGuennadi Liakhovetski1-2/+2
The default format conversion table mbus_fmt[] in soc_mediabus.c lists "natural" conversions between media-bus and fourcc pixel formats, that are achieved by storing data from the bus in RAM exactly as it arrives, only possibly padding missing high or low bits. Such data acquisition mode cannot change data endianness, therefore two locations with opposite endianness are erroneous. This change might affest the omap1-camera driver, existing configurations should be verified.

2013-03-18[media] Media: remove incorrect __init/__exit markupsDmitry Torokhov1-3/+3
Even if bus is not hot-pluggable, the devices can be unbound from the driver via sysfs, so we should not be using __exit annotations on remove() methods. The only exception is drivers registered with platform_driver_probe() which specifically disables sysfs bind/unbind attributes. Similarly probe() methods should not be marked __init unless platform_driver_probe() is used.

2013-01-05[media] soc-camera: properly fix camera probing racesGuennadi Liakhovetski1-3/+19
The recently introduced host_lock causes lockdep warnings, besides, list enumeration in scan_add_host() must be protected by holdint the list_lock. OTOH, holding .video_lock in soc_camera_open() isn't enough to protect the host during its building of the pipeline, because .video_lock is per soc-camera device. If, e.g. more than one sensor can be attached to a host and the user tries to open both device nodes simultaneously, host's .add() method can be called simultaneously for both sensors. Fix these problems by holding list_lock instead of .host_lock in scan_add_host() and taking it shortly at the beginning of soc_camera_open(), and using .host_lock to protect host's .add() and .remove() operations only.

Explicit checks for the JPEG pixel format in soc_mbus_bytes_per_line() and soc_mbus_image_size() are superfluous, because also without them these functions will perform correctly. The former will return 0 based on packing == SOC_MBUS_PACKING_VARIABLE and the latter will simply multiply the user-provided line length by the image height to obtain a frame buffer size estimate.
