The algorithms in nvmem core are built with the constraint that bit_offset < 8. If bit_offset is greater the results are wrong. Print an error if the devicetree 'bits' property is outside of the valid range and abort parsing. Signed-off-by:

Since commit d492cc25 ("driver core: device.h: make struct bus_type a const *"), the driver core can properly handle constant struct bus_type, move the nvmem_layout_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.

The MT8183 has not one but two efuse devices. The static name and ID causes the second efuse device to fail to probe, due to duplicate sysfs entries. With the rework of the mtk-socinfo driver, lookup by name is no longer necessary. The custom name can simply be dropped. Signed-off-by:

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by:

The hard IRQ handler vsc_tp_irq() is called with a raw spinlock taken. wake_up() acquires a spinlock, a sleeping lock on PREEMPT_RT. This leads to sleeping in atomic context.
