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/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < git log --format=%s --max-count=1 70b20dd7f897c6c14ab9e0d8400aed520ab5f09b # < make -s -j 10 ARCH=powerpc O=/kisskb/build/linus_44x_fsp2_defconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 44x/fsp2_defconfig # make -s -j 10 ARCH=powerpc O=/kisskb/build/linus_44x_fsp2_defconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- INFO: Uncompressed kernel (size 0x8acc64) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x900000) Image Name: Linux-4.18.0-g70b20dd Created: Thu Aug 16 18:34:57 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3923959 Bytes = 3831.99 kB = 3.74 MB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/linus_44x_fsp2_defconfig_powerpc-5.3 # Build took: 0:01:48.508795
