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-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < git log --format=%s --max-count=1 70b20dd7f897c6c14ab9e0d8400aed520ab5f09b # < make -s -j 10 ARCH=powerpc O=/kisskb/build/linus_ppc40x_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- ppc40x_defconfig # make -s -j 10 ARCH=powerpc O=/kisskb/build/linus_ppc40x_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:183:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:339:21: note: 'pdeo' was declared here /kisskb/src/drivers/tty/serial/8250/8250_core.c: In function 'univ8250_release_irq': /kisskb/src/drivers/tty/serial/8250/8250_core.c:251:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:231:19: note: 'i' was declared here INFO: Uncompressed kernel (size 0x517930) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x517930) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5072bc) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x517930) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x517930) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-4.18.0-g70b20dd Created: Thu Aug 16 16:52:57 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2545108 Bytes = 2485.46 kB = 2.43 MB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-4.18.0-g70b20dd Created: Thu Aug 16 16:52:57 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2572072 Bytes = 2511.79 kB = 2.45 MB Load Address: 00600000 Entry Point: 00601534 Image Name: Linux-4.18.0-g70b20dd Created: Thu Aug 16 16:52:57 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2570437 Bytes = 2510.19 kB = 2.45 MB Load Address: 00600000 Entry Point: 00601350 Completed OK # rm -rf /kisskb/build/linus_ppc40x_defconfig_powerpc # Build took: 0:01:13.049505
