If the input command length is larger than the kernel supports an error should be returned in case the unsupported bytes are not cleared, instead of the other way aroudn.

Following commit 9427ecbed46cc ("gpio: Rework of_gpiochip_set_names() to use device property accessors"), "gpio-line-names" DT property is not retrieved anymore when chip->parent is not set by the driver. This is due to OF based property reads having been replaced by device based property reads. This patch fixes that by making use of fwnode_property_read_string_array() instead of device_property_read_string_array() and handing over either of_fwnode_handle(chip->of_node) or dev_fwnode(chip->parent) to that function.

Since the recent remote cpufreq callback work, its possible that a cpufreq update is triggered from a remote CPU. For single policies however, the current code uses the local CPU when trying to determine if the remote sg_cpu entered idle or is busy. This is incorrect.

The checks for whether another region/block header could be present are subtracting the size from the current offset. Obviously we should instead subtract the offset from the size. The checks for whether the region/block data fit in the file are adding the data size to the current offset and header size, without checking for integer overflow. Rearrange these so that overflow is impossible.
