[PATCH v2 03/10] soc: sunxi: sram: Actually claim SRAM regions
From: Samuel Holland
Date: Mon Aug 15 2022 - 00:13:13 EST
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.
