* Move the definition for the variable "ret" into an if branch so that an extra initialisation can be avoided at the beginning by this refactoring. * Return a success code as a constant at the end. Signed-off-by:

* A multiplication for the size determination of a memory allocation indicated that an array data structure should be processed. Thus use the corresponding function "kmalloc_array". This issue was detected by using the Coccinelle software. * Replace the specification of a data type by a pointer dereference to make the corresponding size determination a bit safer according to the Linux coding style convention.

This patch derives from previous one(s) by CrazyCat. I used the commit adding rev.3 to mainline Linux kernel as an example, so credits go to its author(s). The hardware seems to scan and tune OK. Signed-off-by:

Simplify the remove function and the error path in the probe function by using the managed versions of rc_allocate_device and rc_register_device. Signed-off-by:

Heiner Kallweit authored
Introduce managed versions of both functions. They allows to simplify the error path in the probe function of rc drivers, and usually also to simplify the remove function. New element managed_alloc in struct rc_dev is needed to correctly handle mixed use, e.g. managed version of rc_register_device and normal version of rc_allocate_device. In addition devm_rc_allocate_device sets rc->dev.parent as having a reference to the parent device might be useful for future extensions. Signed-off-by:

Moving the pxa_camera driver from soc_camera lots the implied VIDEO_V4L2 Kconfig dependency, and building the driver without V4L2 results in a kernel that cannot link: drivers/media/platform/pxa_camera.o: In function `pxa_camera_remove': pxa_camera.c:(.text.pxa_camera_remove+0x10): undefined reference to `v4l2_clk_unregister' pxa_camera.c:(.text.pxa_camera_remove+0x18): undefined reference to `v4l2_device_unregister' drivers/media/platform/pxa_camera.o: In function `pxa_camera_probe': pxa_camera.c:(.text.pxa_camera_probe+0x458): undefined reference to `v4l2_of_parse_endpoint' drivers/media/v4l2-core/videobuf2-core.o: In function `__enqueue_in_driver': drivers/media/v4l2-core/videobuf2-core.o: In function `vb2_core_streamon': videobuf2-core.c:(.text.vb2_core_streamon+0x1b4): undefined reference to `v4l_vb2q_enable_media_source' drivers/media/v4l2-core/videobuf2-v4l2.o: In function `vb2_ioctl_reqbufs': videobuf2-v4l2.c:(.text.vb2_ioctl_reqbufs+0xc): undefined reference to `video_devdata' This adds back an explicit dependency.

There is only one waiter for the completion, therefore there is no need to use complete_all(). Let's make that clear by using complete() instead of complete_all(). While we are at it, we do a small optimization with the reinitialization of the completion before we use it. The usage pattern of the completion is: waiter context waker context send_packet() reinit_completion() usb_sumbit_urb() wait_for_completion_interruptible() usb_tx_callback() complete() imon_disconnect() complete() Signed-off-by:Daniel Wagner <daniel.wagner@bmw-carit.de> Signed-off-by:
