[PATCH v2 0/5] treewide: remove unreachable memblock_reserve() return value checks in early boot

[Sang-Heon Jeon <ekffu200098@gmail.com>]

memblock_reserve() can only return an error after memblock_allow_resize()
has been called. Before that it either succeeds or panics, never returning
an error.

Before memblock_allow_resize() is called, the return value checks of
memblock_reserve() are unreachable and can be removed.

All the call sites are in different trees, so I split the change into one
patch per arch/subsystem. The patches are independent and can be applied
separately.

Hello Mike,

Like the previous memblock cleanup series, could you review and take this patch series to the memblock tree?

Thank you for taking valuable time.

Best Regards,
