Subject: [PATCH v10 05/15] mmc: sdhci-msm: fix crypto key eviction
Date: Thu, 12 Dec 2024 20:19:48 -0800 [thread overview]
Message-ID: <20241213041958.202565-6-ebiggers@kernel.org> (raw)
In-Reply-To: <20241213041958.202565-1-ebiggers@kernel.org>
From: Eric Biggers <ebiggers@google.com>
Commit c7eed31e235c ("mmc: sdhci-msm: Switch to the new ICE API")
introduced an incorrect check of the algorithm ID into the key eviction
path, and thus qcom_ice_evict_key() is no longer ever called. Fix it.
