Sorry for the noise. /ac From: Alex Chiang Subject: [PATCH 1/2] ia64: Remove printk noise on unimplemented SAL_PHYSICAL_ID_INFO Commit 113134fcbca83619be4c68d0ca66db6093777b5d changed the flow of control when calling PAL_LOGICAL_TO_PHYSICAL and SAL_PHYSICAL_ID_INFO. With the change, if a platform did not implement the latter, a useless printk would appear in the boot log: ia64_sal_pltid failed with -1 So let's check the return code and only printk on a true error, and do not print anything in the unimplemented case. While we're in there, clean up some stylistic issues too.
