[U-Boot] [PATCH v2 31/40] env: Drop the ENTRY typedef
Simon Glass
sjg at chromium.org
Thu Aug 1 15:47:06 UTC 2019
U-Boot is not supposed to use typedef for structs anymore. Also this name
is the same as the ENTRY() macro used in assembler files, and 'entry'
itself is widely used in U-Boot (>8k matches).
Drop the typedef and rename the struct to env_entry to reduce confusion.
