Subject: [PATCH v2 30/30] misc: cxl: flash: Remove unused pointer
Date: Wed, 1 Jul 2020 09:31:18 +0100 [thread overview]
Message-ID: <20200701083118.45744-31-lee.jones@linaro.org> (raw)
In-Reply-To: <20200701083118.45744-1-lee.jones@linaro.org>
The DRC index pointer us updated on an OPCODE_ADD, but never
actually read. Remove the used pointer and shift up OPCODE_ADD
to group with OPCODE_DELETE which also provides a noop.
Fixes the following W=1 kernel build warning:
drivers/misc/cxl/flash.c: In function ‘update_devicetree’:
drivers/misc/cxl/flash.c:178:16: warning: variable ‘drc_index’ set but not used [-Wunused-but-set-variable]
178 | __be32 *data, drc_index, phandle;
| ^~~~~~~~~
