Subject: [U-Boot] [PATCH] common/console.c: Fix unused warning with console_doenv()
Date: Wed, 30 Oct 2019 09:18:43 -0400	[thread overview]
Message-ID: <20191030131843.15343-1-trini@konsulko.com> (raw)

Newer versions of LLVM-7 will provide an unused function warning over
console_doenv() in the case of SYS_CONSOLE_IS_IN_ENV not being enabled
as can be the case in SPL.  Add guards around this function.
