From fd362baad2e659ef0fb5652f023a606b248f1781 Mon Sep 17 00:00:00 2001 From: Samuel Holland Date: Sun, 14 Aug 2022 23:12:40 -0500 Subject: soc: sunxi: sram: Actually claim SRAM regions sunxi_sram_claim() checks the sram_desc->claimed flag before updating the register, with the intent that only one device can claim a region. However, this was ineffective because the flag was never set.
