2020-06-14treewide: replace '---help---' in Kconfig files with 'help'Masahiro Yamada
Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

2020-05-28mt76: fix wcid allocation issuesFelix Fietkau
mt76 core uses ffs() to find the next free bit. This works well for 32 bit architectures where BITS_PER_LONG is 32. ffs only checks 32 bit values, so allocation fails on 64 bit architectures. Additionally, the wcid mask array was too small in cases where the array was not a multiple of BITS_PER_LONG. Fix this by making the wcid mask array u32 instead and use DIV_ROUND_UP for the size, just in case we ever bump it to a value that's not a multiple of 32.
