2023-07-18spi: spi-fsl-lpspi: Move controller initialization further downAlexander Stein1-16/+16
This is a preparation for reading number of chip-selects from hardware. This needs IO resources mapped and peripheral clocking enabled. No functional changes intended.

2023-07-14spi: Explicitly include correct DT includesRob Herring43-48/+26
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-07-14spi: Use struct_size() helperAndy Shevchenko1-6/+9
The Documentation/process/deprecated.rst suggests to use flexible array members to provide a way to declare having a dynamically sized set of trailing elements in a structure.This makes code robust agains bunch of the issues described in the documentation, main of which is about the correctness of the sizeof() calculation for this data structure. Due to above, prefer struct_size() over open-coded versions.

2023-07-10spi: rzv2m-csi: Convert to platform remove callback returning voidUwe Kleine-König1-4/+2
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() is renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

We just sorted the entries and fields last release, so just out of a perverse sense of curiosity, I decided to see if we can keep things ordered for even just one release. The answer is "No. No we cannot". I suggest that all kernel developers will need weekly training sessions, involving a lot of Big Bird and Sesame Street. And at the yearly maintainer summit, we will all sing the alphabet song together. I doubt I will keep doing this.

2023-07-09mm: lock newly mapped VMA with corrected orderingHugh Dickins1-2/+2
Lockdep is certainly right to complain about (&vma->vm_lock->lock){++++}-{3:3}, at: vma_start_write+0x2d/0x3f but task is already holding lock: (&mapping->i_mmap_rwsem){+.+.}-{3:3}, at: mmap_region+0x4dc/0x6db Invert those to the usual ordering. Fixes: 33313a747e81 ("mm: lock newly mapped VMA which can be modified after it becomes visible") Cc: stable@vger.kernel.org Signed-off-by: Hugh Dickins <hughd@google.com> Tested-by: Suren Baghdasaryan <surenb@google.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
