From 447c5dd7338638f526e9bcf7dcf69b4da5835c7d Mon Sep 17 00:00:00 2001 From: Michal Schmidt Date: Tue, 11 May 2010 11:44:54 +0200 Subject: PCI: return correct value when writing to the "reset" attribute A successful write() to the "reset" sysfs attribute should return the number of bytes written, not 0. Otherwise userspace (bash) retries the write over and over again. Acked-by: Michael S.
