From 84ae7d9cfa5f6ec284efccedcb7baf7c075774d4 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Thu, 4 Apr 2024 10:38:45 +0300 Subject: [PATCH] ASoC: SOF: Disable pointless writes to debugfs file The permissions on this debugfs file are 0444 so it can't be written to. And writing to the file hasn't done anything since commit 6e9548cdb30e ("ASoC: SOF: Convert the generic IPC flood test into SOF client"). Delete the write function.
