From fcafadf71a252009f1d0663b8fcf4bd57f4f2c66 Mon Sep 17 00:00:00 2001 From: Chunfeng Yun Date: Wed, 17 Apr 2019 16:28:20 +0800 Subject: usb: chipidea: msm: get optional clock by devm_clk_get_optional() When the driver tries to get optional clock, it ignores all errors except -EPROBE_DEFER, but if only ignores -ENOENT, it will cover some real errors, such as -ENOMEM, so use devm_clk_get_optional() to get optional clock.
