Subject: [PATCH v2 12/19] block: parse partition table on block device registration
Date: Wed,  7 Jun 2023 14:07:07 +0200	[thread overview]
Message-ID: <20230607120714.3083182-13-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20230607120714.3083182-1-a.fatoum@pengutronix.de>

Every instance of block device registration is followed by an
attempt to parse the partition table. Thus move partition table
parsing into blockdevice_register.

We do away with the warning print as it's superfluous:
parse_partition_table doesn't return an error if partition table is
missing and all other errors already result in an error message.

v1 -> v2:
  - remove extra warning if parse_partition_table fails
  - Add Marco's Reviewed-by
