kernel.git/drivers/visorbus/visorchipset.c, branch linux-5.11.yHosts the 0x221E linux distro kernel.
https://git.0xinfinity.dev/distro/kernel.git/atom?h=linux-5.11.y2020-01-14T14:30:35Zvisorbus: fix uninitialized variable access2020-01-14T14:30:35ZArnd Bergmann2020-01-07T20:29:40Zurn:sha1:caf82f727e69b647f09d57a1fc56e69d22a5f483
The setup_crash_devices_work_queue function only partially initializes
the message it sends to chipset_init, leading to undefined behavior:
drivers/visorbus/visorchipset.c: In function 'setup_crash_devices_work_queue':
drivers/visorbus/visorchipset.c:333:6: error: '((unsigned char*)&msg.hdr.flags)[0]' is used uninitialized in this function [-Werror=uninitialized]
if (inmsg->hdr.flags.response_expected)
Set up the entire structure, zero-initializing the 'response_expected'
flag.
This was apparently found by the patch that added the -O3 build option
in Kconfig.

drivers: visorbus: move driver out of staging2017-12-08T15:37:50ZDavid Kershner2017-12-07T17:11:07Zurn:sha1:93d3ad90c2d470804b16f79e7e872408747d3e77
Move the visorbus driver out of staging (drivers/staging/unisys/visorbus)
and to drivers/visorbus. Modify the configuration and makefiles so they
now reference the new location. The s-Par header file visorbus.h that is
referenced by all s-Par drivers, is being moved into include/linux.
