From 1f5571cb1d7be29df8d4cc4cb6ab1c6a5039ee54 Mon Sep 17 00:00:00 2001 From: Nathan Lynch Date: Fri, 18 Nov 2022 09:07:43 -0600 Subject: [PATCH] powerpc/pseries/eeh: use correct API for error log size [ Upstream commit 9aafbfa5f57a4b75bafd3bed0191e8429c5fa618 ] rtas-error-log-max is not the name of an RTAS function, so rtas_token() is not the appropriate API for retrieving its value. We already have rtas_get_error_log_max() which returns a sensible value if the property is absent for any reason, so use that instead.
