Merge tag 'gpio-v4.4-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO fixes from Linus Walleij:
"Some GPIO fixes for the v4.4 series:
- Fix a bunch of possible NULL references found by Coccinelle
jockeys.
- Stop creating Tegra's debugfs on everything and its dog. This is
an ARM multiplatform kernel issue.
- Fix an oops in gpiolib for NULL names on named GPIOs.
- Fix a complex OMAP1 bug in the OMAP driver"
* tag 'gpio-v4.4-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio:
gpio: omap: drop omap1 mpuio specific irq_mask/unmask callbacks
gpiolib: fix oops, if gpio name is NULL
gpio-tegra: Do not create the debugfs entry by default
gpio: palmas: fix a possible NULL dereference
gpio: syscon: fix a possible NULL dereference
gpio: 74xx: fix a possible NULL dereference
