Subject: [PATCH v2 09/20] power: supply: bq25890: Drop dev->platform_data == NULL check
Date:   Sun, 14 Nov 2021 18:03:24 +0100

Drop the "if (!dev->platform_data)" check, this seems to be an attempt
for allowing loading the driver on devices without devicetree stemming
from the initial commit of the driver (with the presumed intention being
the "return -ENODEV" else branch getting replaced with something else).

With the new "linux,skip-init" and "linux,read-back-settings" properties
the driver can actually supports devices without devicetree and this
check no longer makes sense.

While at it also switch to dev_err_probe(), which is already used in
various other places in the driver.
