The struct prototype is defined at the beginning of the code as "si2157_ops" but the real struct is called "si2157_tuner_ops". This is causing the name to be empty on this info msg: si2157 16-0060: si2157: found a '' in cold state [crope@iki.fi: commit msg from Luis email reply] Signed-off-by:

Implement unlocked variants of v4l2_ctrl_s_ctrl() and v4l2_ctrl_s_ctrl_int64(). As drivers need to set controls as they access driver internal state elsewhere than in the control framework unlocked variants of these functions become handy. Signed-off-by:

Drivers may use the v4l2_ctrl_modify_range() internally as part of other operations that need to be both serialised using a driver's lock which can also be used to serialise access to the control handler. Provide an unlocked version of the function, __v4l2_ctrl_modify_range() which then may be used by drivers for the purpose. Signed-off-by:

OVL and BTP IRAM buffers are never used, setup the bits for for DBK/BIT/IP usage depending on CODA version in one place. Also, use a simple allocator function and group IRAM addresses and size in a coda_aux_buf structure. This is done in preparation for CODA960 support. Signed-off-by:
