Subject: [PATCH v2 20/32] common/cnxk: access valid pass value
Date: Wed, 24 May 2023 15:33:55 +0530 [thread overview]
Message-ID: <20230524100407.3796139-20-ndabilpuram@marvell.com> (raw)
In-Reply-To: <20230524100407.3796139-1-ndabilpuram@marvell.com>
From: Hanumanth Pothula <hpothula@marvell.com>
There is a possibility of accessing an invalid pass value on
rvu device look up failure, as the return value is dropped.
Hence pass through the return value of rvu device look, to make
sure valid pass value is accessed.
