2018-03-15mailbox: tegra: relax TEGRA_HSP_MBOX Kconfig dependenciesArnd Bergmann
With the addition of the ARCH_TEGRA_194_SOC driver, we get a new Kconfig warning: warning: (ARCH_TEGRA_186_SOC && ARCH_TEGRA_194_SOC) selects TEGRA_HSP_MBOX which has unmet direct dependencies (MAILBOX && ARCH_TEGRA_186_SOC) It looks like the dependency is a bit too strict here, allowing the driver to be built for any Tegra chip avoids the problem.

2018-03-15mtd: rawnand: remove STANDALONE compile mode of nand_eccMasahiro Yamada
This file can not be built independently any more. We would have to bring in more to resolve mtd_to_nand(mtd)->ecc.size, for example. It is difficult to notice a breakage since nobody compiles this mode. It is not worth fixing or maintaining in my opinion. Remove.

2018-03-15drm/radeon: Don't turn off DP sink when disconnectedMichel Dänzer
Turning off the sink in this case causes various issues, because userspace expects it to stay on until it turns it off explicitly. Instead, turn the sink off and back on when a display is connected again. This dance seems necessary for link training to work correctly.

2018-03-15mmc: block: fix updating ext_csd caches on ioctl callBastian Stender
PARTITION_CONFIG is cached in mmc_card->ext_csd.part_config and the currently active partition in mmc_blk_data->part_curr. These caches do not always reflect changes if the ioctl call modifies the PARTITION_CONFIG registers, e.g. by changing BOOT_PARTITION_ENABLE. Write the PARTITION_CONFIG value extracted from the ioctl call to the cache and update the currently active partition accordingly. This ensures that the user space cannot change the values behind the kernel's back. The next call to mmc_blk_part_switch() will operate on the data set by the ioctl and reflect the changes appropriately.
