From 6b0d35891c835319291f2c3b459e666fc809f831 Mon Sep 17 00:00:00 2001 From: Venkatesh Yadav Abbarapu Date: Mon, 12 Aug 2019 15:36:42 +0530 Subject: [PATCH] can: xilinx_can: xcan_probe(): skip error message on deferred probe When can clock is provided from the clock wizard, clock wizard driver may not be available when can driver probes resulting to the error message "Device clock not found error". As this error message is not very userful to the end user, skip printing it in the case of deferred probe.
