[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. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
