From fd5ef3d69f8975bad16c437a337b5cb04c8217a2 Mon Sep 17 00:00:00 2001 From: Can Peng Date: Thu, 23 Oct 2025 10:42:50 +0800 Subject: [PATCH] spi: spi-qpic-snand: make qcom_spi_ecc_engine_ops_pipelined const Marking the qcom_spi_ecc_engine_ops_pipelined as const provides memory protection by preventing accidental modification of critical function pointers at runtime. It also enables memory optimization by placing the structure in read-only sections and improves code safety by explicitly documenting the design intent that these operations should not change after initialization.
