Pull misc fixes from Miguel Ojeda: "A trivial patch for auxdisplay: - Replace HTTP links with HTTPS ones (Alexander A. Klimov) The usual clang-format trivial update: - Update with the latest for_each macro list (Miguel Ojeda) And Luc requested me to pick a sparse fix on my queue, so here it goes along with other two trivial Compiler Attributes ones (also from Luc). - sparse: use static inline for __chk_{user,io}_ptr() (Luc Van Oostenryck) - Compiler Attributes: fix comment concerning GCC 4.6 (Luc Van Oostenryck) - Compiler Attributes: remove comment about sparse not supporting __has_attribute (Luc Van Oostenryck)" * tag 'auxdisplay-for-linus-v5.9-rc4' of git://github.com/ojeda/linux: auxdisplay: Replace HTTP links with HTTPS ones * tag 'clang-format-for-linus-v5.9-rc4' of git://github.com/ojeda/linux: clang-format: Update with the latest for_each macro list * tag 'compiler-attributes-for-linus-v5.9-rc4' of git://github.com/ojeda/linux: sparse: use static inline for __chk_{user,io}_ptr() Compiler Attributes: fix comment concerning GCC 4.6 Compiler Attributes: remove comment about sparse not supporting __has_attribute
