Charles Haithcock 1c72e7b0b4 i2c: i801: Revert "i2c: i801: replace acpi_lock with I2C bus lock" 
[ Upstream commit cfc69c2e6c ]

This reverts commit f707d6b9e7.

Under rare circumstances, multiple udev threads can collect i801 device
info on boot and walk i801_acpi_io_handler somewhat concurrently. The
first will note the area is reserved by acpi to prevent further touches.
This ultimately causes the area to be deregistered. The second will
enter i801_acpi_io_handler after the area is unregistered but before a
check can be made that the area is unregistered. i2c_lock_bus relies on
the now unregistered area containing lock_ops to lock the bus. The end
result is a kernel panic on boot with the following backtrace;

The kernel panic is mitigated by setting limiting the count of udev
children to 1. Revert to using the acpi_lock to continue protecting
marking the area as owned by firmware without relying on a lock in
a potentially unmapped region of memory.
