From 607e9316d3bd64ea6c1f7193ff9a7085a272244e Mon Sep 17 00:00:00 2001 From: Daniel Henrique Barboza Date: Thu, 11 Aug 2022 13:39:48 -0300 Subject: [PATCH] ppc/pnv: change pnv_phb4_get_pec() to also retrieve chip10->pecs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The function assumes that we're always dealing with a PNV9_CHIP() object. This is not the case when the pnv-phb device belongs to a powernv10 machine. Change pnv_phb4_get_pec() to be able to work with PNV10_CHIP() if necessary.
