Subject: [PATCH v2 1/2] uncompress: use read_full to fill decompression buffer
Date: Wed, 26 May 2021 11:02:15 +0200	[thread overview]
Message-ID: <20210526090216.4003977-1-l.stach@pengutronix.de> (raw)

The decompression algorithms want all of the requested buffer size
to be filled and don't cope with less bytes being returned.
Use read_full to satisfy this requirement.
