As stated in the MPEG-2 specification, section 6.3.7 "Quant matrix extension": Each quantisation matrix has a default set of values. When a sequence_header_code is decoded all matrices shall be reset to their default values. User defined matrices may be downloaded and this can occur in a sequence_header() or in a quant_matrix_extension(). The load_intra_quantiser_matrix syntax elements are transmitted in the bitstream headers, signalling that a quantisation matrix needs to be loaded and used for pictures transmitted afterwards (until the matrices are reset). This "load" semantics are implemented in the V4L2 interface without the need of any "load" flags: passing the control is effectively a load. Therefore, rework the V4L2_CID_MPEG_VIDEO_MPEG2_QUANTISATION semantics to match the MPEG-2 semantics. Quantisation matrices values are now initialized by the V4L2 control core to their reset default value, and applications are expected to reset their values as specified. The quantisation control is therefore optional, and used to load bitstream-defined values in the quantisation matrices. Signed-off-by:

The MPEG-2 specification refers to the quantisation matrices using the word "quantisation". Make the V4L2 interface more ergonomic by matching the MPEG-2 spec. Signed-off-by:

The adapter count is fixed at compile time so we can delete the lme2510_get_adapter_count() function and set ".num_adapters = 1" instead. There is also no need to create a zeroed adapter element at the end of the array. Remove that as well. Signed-off-by:

'ret' is known to be 1 here. In fact 'i' is expected instead. Store the return value of 'i2c_master_recv()' in 'ret' so that the error message print the correct error code. Fixes: acaa34bf ("media: rc: implement zilog transmitter") Signed-off-by:

I came across a randconfig build failure from one driver that only depends on CONFIG_USB_ARCH_HAS_HCD but fails when built without CONFIG_USB: ld: drivers/media/rc/ir_toy.o: in function `irtoy_disconnect': ir_toy.c:(.text+0x24): undefined reference to `usb_kill_urb' ld: ir_toy.c:(.text+0x2c): undefined reference to `usb_free_urb' ld: ir_toy.c:(.text+0x34): undefined reference to `usb_kill_urb' ld: ir_toy.c:(.text+0x3c): undefined reference to `usb_free_urb' Upon a closer look, I find that a lot of the other drivers 'select USB' rather than stating 'depends on USB' as is common for most subsystems. I also find that all except one driver have an extra 'depends on RC_CORE' that is already implied by the top-level 'if RC_CORE' check. Clean up both by reducing the dependencies to the required set.

Commit dd8088d5 ("PM: runtime: Add pm_runtime_resume_and_get to deal with usage counter") added pm_runtime_resume_and_get() in order to automatically handle dev->power.usage_count decrement on errors. While there's nothing wrong with the current usage on this driver, as we're getting rid of the pm_runtime_get_sync() call all over the media subsystem, let's remove the last occurrence on this driver.

Use the new API, in order to cleanup the error check logic. While here, as noted by Phillip, the labels at the coda_open() function are currently named after what operation failed, instead of what they do in response. So, change the name of the error label that it is called when clk_enable fails, in order to be consistent. Reviewed-by:
