Subject: [PATCH] fpga: dfl: fme: Constify static attribute_group structs
Date: Sat,  9 Jan 2021 00:54:14 +0100	[thread overview]
Message-ID: <20210108235414.48017-1-rikard.falkeborn@gmail.com> (raw)

The only usage of these is to put their addresses in arrays of pointers
to const attribute_groups. Make them const to allow the compiler to put
them in read-only memory.
