In eeh_add_device_late(), pdn is NULL, so edev is NULL and # we oops. # # We never had explicit support for EEH for those virtual devices. # Instead, EEH events are reported to the (real) pci device and handled # by the cxl driver. Which can then forward to the virtual devices and # handle dependencies. The fact that we try adding EEH support for the # virtual devices is new and a side-effect of the recent cleanup. # # This patch fixes it by skipping adding EEH support on powernv for # devices which don't have a pci_dn structure. # # The cxl driver doesn't create virtual devices on pseries so this patch # doesn't fix it there intentionally. # # Fixes: b905f8cdca77 ("powerpc/eeh: EEH for pSeries hot plug") # Signed-off-by: Frederic Barrat <fbarrat@linux.ibm.com> # Reviewed-by: Sam Bobroff <sbobroff@linux.ibm.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20191016162833.22509-1-fbarrat@linux.ibm.com # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 a8a30219ba78b1abb92091102b632f8e9bbdbf03 # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc6xx_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc6xx_defconfig # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc6xx_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/sound/ppc/pmac.h:12:0, from /kisskb/src/sound/ppc/awacs.c:16: /kisskb/src/sound/ppc/awacs.c: In function 'snd_pmac_awacs_init': /kisskb/src/include/sound/control.h:208:9: warning: 'speaker_vol' may be used uninitialized in this function [-Wmaybe-uninitialized] return _snd_ctl_add_slave(master, slave, 0);
