Subject: [PATCH net v2 2/2] gve: Propagate error codes to caller
Date: Thu,  1 Jul 2021 22:18:37 +0200	[thread overview]
Message-ID: <2a1bcfa7f84f63ab2076175c6a5c0a5a181d3bcb.1625170569.git.christophe.jaillet@wanadoo.fr> (raw)
In-Reply-To: <f5dbb1ed01d13d4eac2b719db42cb02bf8166ceb.1625170569.git.christophe.jaillet@wanadoo.fr>

If 'gve_probe()' fails, we should propagate the error code, instead of
hard coding a -ENXIO value.
Make sure that all error handling paths set a correct value for 'err'.
