2020-05-01ASoC: SOF/Intel: clarify SPDX license with GPL-2.0-onlyPierre-Louis Bossart1-1/+1

2020-04-16ASoC: SOF: make sof_ipc_cc_version to fixed lengthPan Xiuli1-1/+1
Align struct sof_ipc_cc_version to firmware definition in SOF ABI 3.15.0. The struct definition was changed due to errors in FW build. The Cadence XCC compiler produces incorrect linkage section sizes, when a variable length array is used in the compiler version struct. The firmware definition was changed to a fixed 32 byte compiler description string. This length covers all released firmware binaries and thus only a minor ABI change is needed. As the same structure is used in IPC messages between driver and firmware, the kernel needs to be aligned to firmware change.

2019-07-25treewide: remove SPDX "WITH Linux-syscall-note" from kernel-space headers againMasahiro Yamada1-1/+1
The "WITH Linux-syscall-note" exception exists for headers exported to user space. It is strange to add it to non-exported headers. Commit 687a3e4d8e61 ("treewide: remove SPDX "WITH Linux-syscall-note" from kernel-space headers") did cleanups some months ago, but it looks like we need to do this periodically. This patch was generated by the following script: git grep -l -e Linux-syscall-note \ -- :*.h :^arch/*/include/uapi/asm/*.h :^include/uapi/ :^tools | while read file do sed -i -e 's/(\(GPL-[^[:space:]]*\) WITH Linux-syscall-note)/\1/g' \ -e 's/ WITH Linux-syscall-note//g' $file done I did not commit drivers/staging/android/uapi/ion.h . This header is not currently exported, but somebody may plan to move it to include/uapi/ when the time comes. I am not sure. Anyway, it will be better to check the license inconsistency in drivers/staging/android/uapi/.
