Subject: OpenULINK firmware: Use C99 designated struct initializers
X-Git-Tag: v0.8.0-rc1~354
X-Git-Url: https://repo.or.cz/w/openocd.git/commitdiff_plain/7f32136238f6b7e7e12cfbcb495ea467a43c7ee7

OpenULINK firmware: Use C99 designated struct initializers

Recent versions of SDCC added support for C99 designated struct initializers.
This provides better code readability (no functional changes).

Successfully tested with ULINK probe and STM32F103 (debug, erase and write
flash).
