Merge tag 'char-misc-3.9-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc fixes from Greg Kroah-Hartman:
"Here are some tiny fixes for the w1 drivers and the final removal
patch for getting rid of CONFIG_EXPERIMENTAL (all users of it are now
gone from your tree, this just drops the Kconfig item itself.)
All have been in the linux-next tree for a while"
* tag 'char-misc-3.9-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc:
final removal of CONFIG_EXPERIMENTAL
w1: fix oops when w1_search is called from netlink connector
w1-gpio: fix unused variable warning
w1-gpio: remove erroneous __exit and __exit_p()
ARM: w1-gpio: fix erroneous gpio requests
