2016-02-03PM / Domains: Silence compiler warning for an unused functionUlf Hansson1-20/+7
The only remaining caller of genpd_poweron() is conditionally compiled based on CONFIG_PM_GENERIC_DOMAINS_OF, so we get a warning when that is unset. By moving the locking/unlocking of the genpd outside genpd_poweron(), thus to the caller, genpd_poweron() becomes redundant. Within this context let's then rename the wrapper function, __genpd_poweron(), to genpd_poweron() as it will then be consistent with its friend genpd_poweroff(). This change silence the warning about the unused function.

2016-02-02mailbox: pcc: fix channel calculation in get_pcc_channel()Alexey Klimov1-7/+1
This patch fixes the calculation of pcc_chan for non-zero id. After the compiler ignores the (unsigned long) cast the pcc_mbox_channels pointer is type-cast and then the type-cast offset is added which results in address outside of the range leading to the kernel crashing. We might add braces and make it: pcc_chan = (struct mbox_chan *) ((unsigned long) pcc_mbox_channels + (id * sizeof(*pcc_chan))); but let's go with array approach here and use id as index.

This set comprises those not dependent on patches in the 4.5 merge cycle. A second set will follow shortly with ones that are. * core in kernel interfaces - fix a possible NULL dereference that is a theoretical possibility via odd usage of iio_channel_release. Pretty much a hardening of the interface, but observed in the wild with the twl4030_charger driver. * acpi-als - report the data as processed as it is in lux. This fixes a wrong use of the IIO ABI. However, old _raw version retained to avoid breaking any userspace in the wild that is relying on that (none known but it doesn't hurt us much to retain it) * ade7753 - fix some error handling to avoid use of unitialized data. * ltr501 - use a signed return type for ltr501_match_samp_freq so as to allow returning of an error code. * mcp4725 - set name field of struct iio_dev to ensure the sysfs name attribute doesn't give NULL. * mpl115 - temperature offset sign is wrong. * stk8ba50 - IIO_TRIGGER dependency added * ti_am335x_adc - Label buffer as a software buffer. It's actually a hybrid of a true hardware buffer feeding a kfifo, but the meaning of these fields has changed a little recently and in this case it should be labeled a software buffer ensure it is allowed to use the kfifo. * vf610_adc - HAS_IOMEM dependency

2016-02-01bus: uniphier-system-bus: revive tristate promptMasahiro Yamada1-1/+1
At first, commit 4b7f48d395a7 ("bus: uniphier-system-bus: add UniPhier System Bus driver") introduced this driver as a tristate one. Then, commit 326ea45aa827 ("bus: uniphier: allow only built-in driver") temporarily made it boolean in order to fix a link error in case it is compiled as a module. The root cause was fixed by commit b80443c2211c ("of/platform: export of_default_bus_match_table"). Now this driver can really be a module.

2016-02-01[media] media: i2c: Don't export ir-kbd-i2c module aliasJavier Martinez Canillas1-1/+0
This is a partial revert of commit ed8d1cf07cb16d ("[media] Export I2C module alias information in missing drivers") that exported the module aliases for the I2C drivers that were missing to make autoload to work. But there is a bug report [0] that auto load of the ir-kbd-i2c driver cause the Hauppauge HD-PVR driver to not behave correctly. This is a hdpvr latent bug that was just exposed by ir-kbd-i2c module autoloading working and will also happen if the I2C driver is built-in or a user calls modprobe to load the module and register the driver. But there is a regression experimented by users so until the real bug is fixed, let's not export the module alias for the ir-kbd-i2c driver even when this just masks the actual issue.

for_each_compatible_node performs an of_node_get on each iteration, so to break out of the loop an of_node_put is required. Found using Coccinelle.

2016-02-01drm/exynos: dp: Fix panel and bridge lookup logicJavier Martinez Canillas1-30/+25
Commit a9fa852886fd ("drm/exynos: dp: add of_graph dt binding support for panel") made the Exynos DP DT binding more consistent since the OF graph could be used to lookup either a panel or a bridge device node. Before that commit, a panel would be looked up using a phandle and a bridge using the OF graph which made the DT binding not consistent. But the patch broke the later case since not finding a panel dev node would cause the driver's to do a probe deferral instead of attempting to lookup a bridge device node associated with the remote endpoint. So instead of returning a -EPROBE_DEFER if a panel is not found, check if there's a bridge and only do a probe deferral if both aren't found.

2016-02-01drm: exynos: make PM functions as __maybe_unusedArnd Bergmann1-4/+2
The newly added runtime-pm support for exynos-drm encloses the pm functions in an #ifdef, but not the functions that are called from them and nowhere else, which produces warnings: drm/exynos/exynos_drm_dsi.c:733:13: warning: 'exynos_dsi_disable_clock' defined but not used [-Wunused-function] static void exynos_dsi_disable_clock(struct exynos_dsi *dsi) ^ drm/exynos/exynos_drm_dsi.c:1291:13: warning: 'exynos_dsi_disable_irq' defined but not used [-Wunused-function] static void exynos_dsi_disable_irq(struct exynos_dsi *dsi) ^ This removes the #ifdef and instead marks the functions as __maybe_unused, so gcc can silently discard them and all called functions when CONFIG_PM is disabled.

2016-02-01drm/exynos: fix building without CONFIG_PM_SLEEPArnd Bergmann1-4/+2
The runtime PM operations use the suspend/resume functions even when CONFIG_PM_SLEEP is not set, but this now fails for the exynos DRM driver: exynos_mixer.c:1289:61: error: 'exynos_mixer_resume' undeclared here (not in a function) SET_RUNTIME_PM_OPS(exynos_mixer_suspend, exynos_mixer_resume, NULL) This removes the #ifdef and instead marks the functions as __maybe_unused, which does the right thing in all cases and also looks nicer.
