4cf85459e0 [WATCHDOG] Remove the redundant check for pwrite() in pnx4008 watchdog.
Given that the open routine already calls nonseekable_open(), remove
the redundant check for pwrite().

2b8693c061 [PATCH] mark struct file_operations const 3
Many struct file_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.

f311896a99 [WATCHDOG] use ENOTTY instead of ENOIOCTLCMD in ioctl()
Return ENOTTY instead of ENOIOCTLCMD in user-visible ioctl() results

The watchdog drivers used to return ENOIOCTLCMD for bad ioctl() commands.
ENOIOCTLCMD should not be visible by the user, so use ENOTTY instead.

99d2853ac9 [WATCHDOG] pnx4008_wdt.c - spinlock fixes.
Add io spinlocks to prevent possible race
conditions between start and stop operations
that are issued from different child processes
where the master process opened /dev/watchdog.
