Subject: [PATCH v3] fpga: dfl: remove unused member pdata from struct dfl_{afu,fme}
Date: Mon, 15 Apr 2024 19:59:37 -0400

The member pdata in struct dfl_{afu,fme} is set in function
{afu,fme}_dev_init(), respectively, but never used.

Fixes: 857a26222ff7 ("fpga: dfl: afu: add afu sub feature support")
Fixes: 29de76240e86 ("fpga: dfl: fme: add partial reconfiguration sub feature support")
Signed-off-by: Peter Colberg <peter.colberg@intel.com>
Reviewed-by: Matthew Gerlach <matthew.gerlach@linux.intel.com>
---
v3:
- Do not wrap commit references and move to Fixes: tags.
v2:
- Remove unused member pdata from struct dfl_fme, too.
