Subject: [PATCH v3 3/3] lib kallsyms: move hex2u64 out of header
Date: Tue,  5 May 2020 07:36:25 -0700	[thread overview]
Message-ID: <20200505143625.147832-4-irogers@google.com> (raw)
In-Reply-To: <20200505143625.147832-1-irogers@google.com>

hex2u64 is a helper that's out of place in kallsyms.h as not being kallsyms
related. Move from kallsyms.h to the only user.
