From 9ae3b4e220f019db1a73dbab251d9e63ef87f5da Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Fri, 21 Jun 2019 12:33:57 +0100 Subject: [PATCH] ASoC: dapm: Adapt for debugfs API change Back in 846632d286c9d64 (debugfs: return error values, not NULL) the debugfs APIs were changed to return error pointers rather than NULL pointers on error, breaking the error checking in ASoC. Update the code to use IS_ERR() and log the codes that are returned as part of the error messages.
