From: Chase Douglas Date: Fri, 21 May 2010 16:41:01 +0000 (+0200) Subject: i2c-nforce2: Remove redundant error messages on ACPI conflict X-Git-Tag: firefly_0821_release~9833^2~2071^2 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=7c4fda1aa15fdbbd2563e7e652cd3745f92a16da;p=firefly-linux-kernel-4.4.55.git i2c-nforce2: Remove redundant error messages on ACPI conflict The ACPI subsystem strictly checks for resource conflicts. When there's a conflict, it outputs a warning message with all the details needed to properly diagnose the underlying issue. However, the i2c-nforce2 driver also prints its own message. Not only is the message redundant, it is at the KERN_ERR level, which overrides some bootsplash screens for no good reason. This change removes the two lines that print out the error messages.
