It would see the # registration return zero, which _used_ to mean "failed" but now means # "success", and clear the dell_micmute_led_set_func pointer. # # End result: the successful registration would end up calling the Dell # code that thought it had all failed, and call through a NULL pointer. # # To make matters worse, it ends up being a tail-call, and with the # retpoline sequence you don't even see the caller (dell_micmute_update()) # in the stack trace, so the error ended up way less obvious than it # should have been. # # Fixes: c647f806b8c2 "ALSA: hda - Allow multiple ADCs for mic mute LED controls" # Cc: Takashi Iwai <tiwai@suse.de> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/arcompact-buildroot-2015.08.1/bin/arc-buildroot-linux-uclibc-gcc --version # < git log --format=%s --max-count=1 70b20dd7f897c6c14ab9e0d8400aed520ab5f09b # < make -s -j 48 ARCH=arc O=/kisskb/build/linus_axs101_defconfig_arcompact CROSS_COMPILE=/opt/cross/kisskb/arcompact-buildroot-2015.08.1/bin/arc-buildroot-linux-uclibc- axs101_defconfig # Added to kconfig CONFIG_INITRAMFS_SOURCE="" # make -s -j 48 ARCH=arc O=/kisskb/build/linus_axs101_defconfig_arcompact CROSS_COMPILE=/opt/cross/kisskb/arcompact-buildroot-2015.08.1/bin/arc-buildroot-linux-uclibc- olddefconfig # make -s -j 48 ARCH=arc O=/kisskb/build/linus_axs101_defconfig_arcompact CROSS_COMPILE=/opt/cross/kisskb/arcompact-buildroot-2015.08.1/bin/arc-buildroot-linux-uclibc- In file included from /kisskb/src/include/asm-generic/bug.h:18:0, from /kisskb/src/arch/arc/include/asm/bug.h:32, from /kisskb/src/include/linux/bug.h:5, from /kisskb/src/include/linux/mmdebug.h:5, from /kisskb/src/include/linux/gfp.h:5, from /kisskb/src/include/linux/slab.h:15, from /kisskb/src/mm/nobootmem.c:14: /kisskb/src/mm/nobootmem.c: In function '__free_pages_memory': /kisskb/src/include/linux/kernel.h:812:29: warning: comparison of distinct pointer types lacks a cast [enabled by default] (!!(sizeof((typeof(x) )1 == (typeof(y) )1))) ^ /kisskb/src/include/linux/kernel.h:826:4: note: in expansion of macro '__typecheck' (__typecheck(x, y) && __no_side_effects(x, y)) ^ /kisskb/src/include/linux/kernel.h:836:24: note: in expansion of macro '__safe_cmp' __builtin_choose_expr(__safe_cmp(x, y), \ ^ /kisskb/src/include/linux/kernel.h:845:19: note: in expansion of macro '__careful_cmp' #define min(x, y) __careful_cmp(x, y, <) ^ /kisskb/src/mm/nobootmem.c:104:11: note: in expansion of macro 'min' order = min(MAX_ORDER - 1UL, __ffs(start)); ^ /kisskb/src/net/ipv4/tcp_input.c: In function 'tcp_data_queue': /kisskb/src/net/ipv4/tcp_input.c:4319:49: warning: array subscript is above array bounds [-Warray-bounds] tp->selective_acks[i-1] = tp->selective_acks[i]; ^ Completed OK # rm -rf /kisskb/build/linus_axs101_defconfig_arcompact # Build took: 0:00:48.135044
