linux.git/drivers/char/riscom8.c, branch v2.6.37 Linux kernel source tree riscom8: kill use of lock_kernel 2010-08-10T20:47:40+00:00 Alan Cox alan@linux.intel.com 2010-06-01T20:52:43+00:00 bf936f92a7a564a2cdb44bbe3bc797cd811bf625 The riscom8 board uses lock_kernel to protect bits of the port setting ioctl logic. We can use the port mutex for this as the logic is internal and will also lock set versus open (a locking property that has been lost somewhere along the way) Signed-off-by: Alan Cox <alan@linux.intel.com> Cc: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
