This patch corrects the SPDX License Identifier style in header file related to SLIMbus driver. For C header files Documentation/process/license-rules.rst mandates C-like comments (opposed to C source files where C++ style should be used).

dma_request_slave_channel() is a wrapper on top of dma_request_chan() eating up the error code. By using dma_request_chan() directly the driver can support deferred probing against DMA.

fix below issue reported by coccicheck ./drivers/slimbus/slimbus.h:440:3-46: duplicated argument to && or || Looks like this was a typo, SLIM_MSG_MC_REQUEST_CHANGE_VALUE is command which requires transaction ID, so fix it, this also fix the warning.

Each iteration of for_each_available_child_of_node puts the previous node, but in the case of a return from the middle of the loop, there is no put, thus causing a memory leak. Hence add an of_node_put before the return in two places. Issue found with Coccinelle.

Rely on MODULE_ALIAS() for automatic kernel module loading, rather than basing it on the OF compatible. This ensures that drivers without of_device_id table, such as wcd9335, will be automatically loaded.

The kerneldoc comments in drivers/slimbus/stream.c were not properly formatted, leading to a distinctly unsatisfying "no structured comments found" warning in the docs build. Sprinkle some asterisks around so that the comments will be properly recognized. Signed-off-by: Jonathan Corbet <corbet@lwn.net> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
In case platform_device_alloc fails, the fix returns an error code to avoid the NULL pointer dereference. Signed-off-by: Kangjie Lu <kjlu@umn.edu> Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla@linaro.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
