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/aarch64-linux/bin/aarch64-linux-gcc --version # < git log --format=%s --max-count=1 70b20dd7f897c6c14ab9e0d8400aed520ab5f09b # < make -s -j 20 ARCH=arm64 O=/kisskb/build/linus_arm64-defconfig_arm64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/aarch64-linux/bin/aarch64-linux- defconfig # make -s -j 20 ARCH=arm64 O=/kisskb/build/linus_arm64-defconfig_arm64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/aarch64-linux/bin/aarch64-linux- In function 'kernfs_get_target_path', inlined from 'kernfs_getlink.isra.0' at /kisskb/src/fs/kernfs/symlink.c:118:10, inlined from 'kernfs_iop_get_link.part.1' 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);
