[PATCH] nvmem: core: fix nvmem_cell_write inline function

From: Sebastian Reichel
Date: Sun Sep 08 2019 - 19:19:00 EST

From: Sebastian Reichel <sebastian.reichel@xxxxxxxxxxxxx>

nvmem_cell_write's buf argument uses different types based on
the configuration of CONFIG_NVMEM. The function prototype for
enabled NVMEM uses 'void *' type, but the static dummy function
for disabled NVMEM uses 'const char *' instead. Fix the different
behaviour by always expecting a 'void *' typed buf argument.

Fixes: 7a78a7f7695b ("power: reset: nvmem-reboot-mode: use NVMEM as reboot mode write interface")
