From d98f92371461c5c8cc24e12a212c59b3f437b581 Mon Sep 17 00:00:00 2001 From: Davy Chan Date: Fri, 5 Jan 2007 13:56:46 +0800 Subject: [MIPS] pnx8550: Fix write_config_byte() PCI config space accessor There's a serious typo in the function: arch/mips/pci/ops-pnx8550.c:write_config_byte() The parameter passed to the function config_access() is PCI_CMD_CONFIG_READ instead of PCI_CMD_CONFIG_WRITE. This renders any attempts to write a single byte to the PCI configuration registers useless. This problem does not exist for write_config_word() nor write_config_dword(). This problem has been there since kernel v2.6.17 and is still there as of kernel v2.6.19.1.
