Subject: [PATCH] power: supply: bq27xxx: fix __be16 warnings
The bq27xxx_dm_reg_ptr() should return a __be16 as the result
is being passed to be16_to_cpup() to convert to the proper
cpu endian value. Move to using __be16 as appropriate to fix
the following sparse warnings:
drivers/power/supply/bq27xxx_battery.c:1293:26: warning: incorrect type in argument 1 (different base types)
drivers/power/supply/bq27xxx_battery.c:1293:26: expected restricted __be16 const [usertype] *p
