commit 4a79372b6e6e511c9b7ad5cc97b85338ffb860e3
Author: Antonio Borneo <bor...@gm...>
Date: Tue Dec 27 02:38:25 2022 +0100
target: arc: rewrite command 'arc add-reg' as COMMAND_HANDLER
While there, fix some coding style error and remove the now unused
function jim_arc_read_reg_name_field() and the macro
JIM_CHECK_RETVAL().
