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/korg/gcc-8.1.0-nolibc/hppa64-linux/bin/hppa64-linux-gcc --version # < git log --format=%s --max-count=1 70b20dd7f897c6c14ab9e0d8400aed520ab5f09b # < make -s -j 40 ARCH=parisc O=/kisskb/build/linus_a500_defconfig_parisc64 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/hppa64-linux/bin/hppa64-linux- a500_defconfig # make -s -j 40 ARCH=parisc O=/kisskb/build/linus_a500_defconfig_parisc64 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/hppa64-linux/bin/hppa64-linux- <stdin>:1335:2: warning: #warning syscall rseq not implemented [-Wcpp] In function 'kernfs_get_target_path', inlined from 'kernfs_getlink' at /kisskb/src/fs/kernfs/symlink.c:118:10, inlined from 'kernfs_iop_get_link.part.0' at /kisskb/src/fs/kernfs/symlink.c:136:10, inlined from 'kernfs_iop_get_link': /kisskb/src/fs/kernfs/symlink.c:100:3: warning: 'strncpy' output truncated before terminating nul copying as many bytes from a string as its length [-Wstringop-truncation] strncpy(s + len, kn->name, slen); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/fs/kernfs/symlink.c: In function 'kernfs_iop_get_link': /kisskb/src/fs/kernfs/symlink.c:97:14: note: length computed here int slen = strlen(kn->name); ^~~~~~~~~~~~~~~~ /kisskb/src/fs/ext4/super.c: In function '__save_error_info': /kisskb/src/fs/ext4/super.c:344:2: warning: 'strncpy' specified bound 32 equals destination size [-Wstringop-truncation] strncpy(es->s_last_error_func, func, sizeof(es->s_last_error_func)); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/fs/ext4/super.c:349:3: warning: 'strncpy' specified bound 32 equals destination size [-Wstringop-truncation] strncpy(es->s_first_error_func, func, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ sizeof(es->s_first_error_func)); ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ In function 'fill_kobj_path', inlined from 'kobject_get_path' at /kisskb/src/lib/kobject.c:174:2: /kisskb/src/lib/kobject.c:147:3: warning: 'strncpy' output truncated before terminating nul copying as many bytes from a string as its length [-Wstringop-truncation] strncpy(path + length, kobject_name(parent), cur); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/lib/kobject.c: In function 'kobject_get_path': /kisskb/src/lib/kobject.c:144:13: note: length computed here int cur = strlen(kobject_name(parent)); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ In function '__xfs_xattr_put_listent', inlined from 'xfs_xattr_put_listent' at /kisskb/src/fs/xfs/xfs_xattr.c:204:2: /kisskb/src/fs/xfs/xfs_xattr.c:142:2: warning: 'strncpy' output may be truncated copying between 5 and 9 bytes from a string of length 9 [-Wstringop-truncation] strncpy(offset, prefix, prefix_len); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ In file included from /kisskb/src/arch/parisc/include/asm/atomic.h:10, from /kisskb/src/include/linux/atomic.h:7, from /kisskb/src/arch/parisc/include/asm/bitops.h:13, from /kisskb/src/include/linux/bitops.h:18, from /kisskb/src/include/linux/kernel.h:11, from /kisskb/src/include/linux/list.h:9, from /kisskb/src/include/linux/module.h:9, from /kisskb/src/drivers/scsi/scsi_debug.c:23: /kisskb/src/drivers/scsi/scsi_debug.c: In function 'resp_start_stop': /kisskb/src/arch/parisc/include/asm/cmpxchg.h:48:3: warning: value computed is not used [-Wunused-value] ((__typeof__((ptr)))__xchg((unsigned long)(x), (ptr), sizeof((ptr)))) /kisskb/src/arch/parisc/include/asm/atomic.h:78:30: note: in expansion of macro 'xchg' #define atomic_xchg(v, new) (xchg(&((v)->counter), new)) ^~~~ /kisskb/src/drivers/scsi/scsi_debug.c:1622:2: note: in expansion of macro 'atomic_xchg' atomic_xchg(&devip->stopped, stop); ^~~~~~~~~~~ Completed OK # rm -rf /kisskb/build/linus_a500_defconfig_parisc64 # Build took: 0:00:38.830998
