Subject: [PATCH] power: supply: bq27xxx: Return the value instead of -ENODATA
From: Hermes Zhang <chenhuiz@...s.com>
It might be better to return value (e.g. 65535) instead of an error
(e.g. No data available) for the time property.
Normally a common function will handle the read string and parse to
integer for all the properties, but will have problem when read the
time property because need to handle the NODATA error as non-error.
So it will make simple for application which indicate success when
read a number, otherwise as an error to handle.
