Subject: [PATCH 6/6] firmware: qcom: scm: smc: Narrow 'mempool' variable scope
Date: Tue, 19 Nov 2024 19:33:22 +0100 [thread overview]
Message-ID: <20241119-qcom-scm-missing-barriers-and-all-sort-of-srap-v1-6-7056127007a7@linaro.org> (raw)
In-Reply-To: <20241119-qcom-scm-missing-barriers-and-all-sort-of-srap-v1-0-7056127007a7@linaro.org>
Only part of the __scm_smc_call() function uses 'mempool' variable, so
narrow the scope to make it more readable.
