- Delete seven error messages for a failed memory allocation - Adjust seven checks for null pointers - Use common error handling code in tm6000_usb_probe() - Adjust jump targets so that the function "kfree" will be always called with a non-null pointer. - Delete an initialisation for the local variable "dev" which became unnecessary with this refactoring.

This addresses the wrong behavior of decoder stop command by rewriting it. These new implementation enqueue an empty buffer on the decoder input buffer queue to signal end-of-stream. The client should stop queuing buffers on the V4L2 Output queue and continue queuing/dequeuing buffers on Capture queue. This process will continue until the client receives a buffer with V4L2_BUF_FLAG_LAST flag raised, which means that this is last decoded buffer with data. Signed-off-by:

In case of error, the function platform_device_register_data() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR(). Signed-off-by:

To improve the readability of code, split the format array into two, one for the format description, other for the register configuration. Meanwhile, add the flag member to indicate the format can be achieved from the sensor or be produced by the controller, and rename members related to the register configuration. Also add more formats support: GREY, ARGB444, ARGB555 and ARGB32. Signed-off-by:

To meet the relationship, enable the HCLOCK and ispck during the device probe, "isc_pck frequency is less than or equal to isc_ispck, and isc_ispck is greater than or equal to HCLOCK." Meanwhile, call the pm_runtime_enable() in the right place. Signed-off-by:

A software write operation to the ISC_CLKEN or ISC_CLKDIS register requires double clock domain synchronization and is not permitted when the ISC_SR.SIP is asserted. So add the .prepare and .unprepare ops to make sure the ISC_CLKSR.SIP is unasserted before the write operation to the ISC_CLKEN or ISC_CLKDIS register. Signed-off-by:

Instead of relying on a mix of runtime PM and the s_power() callback, drop the s_power() callback altogether and use runtime PM solely. As device access is required during device power-on and power-off sequences, runtime PM alone cannot tell whether the device is available. Thus the "active" field is introduced in struct smiapp_sensor to tell whether it is safe to write to the device. Consequently there is no need to power on the device whenever a file handle is open. This functionality is removed as well. The user may still control the device power management through sysfs. Autosuspend remains enabled, with 1 s delay. Signed-off-by:

Rockchip RGA is a separate 2D raster graphic acceleration unit. It accelerates 2D graphics operations, such as point/line drawing, image scaling, rotation, BitBLT, alpha blending and image blur/sharpness The driver supports various operations from the rendering pipeline. - copy - fast solid color fill - rotation - flip - alpha blending The code in rga-hw.c is used to configure regs according to operations The code in rga-buf.c is used to create private mmu table for RGA.

On CPUs like AMD's Geode, for example, we shouldn't even try to load microcode because they do not support the modern microcode loading interface. However, we do the family check *after* the other checks whether the loader has been disabled on the command line or whether we're running in a guest. So move the family checks first in order to exit early if we're being loaded on an unsupported family. Reported-and-tested-by:
