From 9b3865749589d67f612d71b447847223b2321408 Mon Sep 17 00:00:00 2001 From: Tero Kristo Date: Thu, 24 Nov 2016 14:58:28 +0200 Subject: [PATCH] watchdog: davinci: add support for deferred probing devm_clk_get can fail with EPROBE_DEFER in case the clock provider is not ready yet. Handle this case gracefully, rather than dumping out a huge warning.
