2019-04-03staging: add missing SPDX lines to Makefile filesGreg Kroah-Hartman1-0/+1
There are a few remaining drivers/staging/*/Makefile files that do not have SPDX identifiers in them. Add the correct GPL-2.0 identifier to them to make scanning tools happy. Reviewed-by: Mukesh Ojha <mojha@codeaurora.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2019-03-29staging: mediatek: addres minor style issues flagged by clang-format.Armando Miraglia1-4/+2
Running clang-format on mtk-hsdma.c I noticed that few lines would not need to be wrapped, since they fit 80 columns. This change changes such lines to better fit the style-guide.

2019-01-15staging: Move ralink-gdma to its own directoryGeorge Hilliard3-939/+0
This is in preparation to allow it and the mt7621-dma drivers to be built separately. They are completely independent pieces of software, and the Kconfig specifies very different requirements.

2019-01-07staging: mt7621-dma: Use struct_size() in devm_kzalloc()Gustavo A. R. Silva1-3/+3
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; void *entry[]; }; instance = devm_kzalloc(dev, sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = devm_kzalloc(dev, struct_size(instance, entry, count), GFP_KERNEL); This code was detected with the help of Coccinelle.
