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.

It actually causes incorrect behaviour due to the "unreachable()" at the end. This tells the compiler that the end of the function will never be reached, which isn't true. The compiler responds by not adding a 'return' instruction, so control simply moves on to whatever bytes come afterwards in memory. In my tested, that was the ralink_restart() function. This means that an attempt to 'halt' the machine would actually cause a reboot. So remove ralink_halt() so that a 'halt' really does halt.

Since commit 3af5a67c86a3 ("MIPS: Fix early CM probing") the MT7621 has not been able to boot. This commit caused mips_cm_probe() to be called before mt7621.c::proc_soc_init(). prom_soc_init() has a comment explaining that mips_cm_probe() "wipes out the bootloader config" and means that configuration registers are no longer available. It has some code to re-enable this config. Before this re-enable code is run, the sysc register cannot be read, so when SYSC_REG_CHIP_NAME0 is read, a garbage value is returned and panic() is called. If we move the config-repair code to the top of prom_soc_init(), the registers can be read and boot can proceed. Very occasionally, the first register read after the reconfiguration returns garbage, so add a call to __sync().

Commit 7383d44b added a pointer pdata which get set to the default platform_data when non was defined in the device. But it did not pass this pointer to the st_sensors_init_sensor call but still used the maybe uninitialized platform_data from dev. This breaks initialization when no platform_data is given and the optional st,drdy-int-pin devicetree option is not set. This commit fixes this.
