Subject: [PATCH 13/16] crypto/dpaa_sec: fix bitmask truncation
Date: Thu, 14 Nov 2024 22:05:50 -0800	[thread overview]
Message-ID: <20241115060738.313190-14-stephen@networkplumber.org> (raw)
In-Reply-To: <20241115060738.313190-1-stephen@networkplumber.org>

The dqrr_held mask is 64 bit but updates were getting truncated
because 1 is of type int (32 bit) and the result shift of int is of
type int (32 bit); therefore any value >= 32 would get truncated.
