Now, since daisy driver is loaded while parport bus is # initialising the list of parport is still empty and it tries to load # the lowlevel driver, which has an alias set to parport_pc, now causes # a deadlock" # # But I don't think the daisy driver should be loaded by the parport # initialization in the first place, so let's revert the whole change. # # If the daisy driver can just initialize separately on its own (like a # driver should), instead of hooking into the parport init sequence # directly, this issue probably would go away. # # Reported-and-bisected-by: Steven Rostedt (VMware) <rostedt@goodmis.org> # Reported-by: Michal Kubecek <mkubecek@suse.cz> # Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> # Cc: Sudip Mukherjee <sudipm.mukherjee@gmail.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux-ld --version # < git log --format=%s --max-count=1 a3ac7917b73070010c05b4485b8582a6c9cd69b6 # < make -s -j 10 ARCH=nds32 O=/kisskb/build/linus_nds32-allyesconfig_nds32le CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux- allyesconfig # make -s -j 10 ARCH=nds32 O=/kisskb/build/linus_nds32-allyesconfig_nds32le CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux- /kisskb/src/mm/mprotect.c: In function 'change_pte_range': /kisskb/src/mm/mprotect.c:42:20: warning: unused variable 'mm' [-Wunused-variable] struct mm_struct mm = vma->vm_mm; ^~ /kisskb/src/drivers/i2c/i2c-core-base.c: In function 'i2c_generic_scl_recovery': /kisskb/src/drivers/i2c/i2c-core-base.c:235:5: warning: 'ret' may be used uninitialized in this function [-Wmaybe-uninitialized] if (ret == -EOPNOTSUPP) ^ /kisskb/src/drivers/input/joystick/analog.c:172:2: warning: #warning Precise timer not defined for this architecture.
