From 340fa9396b4b73fd894a15fe48882c98d74292ce Mon Sep 17 00:00:00 2001 From: Uwe Hermann Date: Wed, 10 Nov 2010 14:53:36 +0000 Subject: Random Winbond Super I/O cosmetic and coding-style fixes. - Whitespace, coding style, and typo fixes. - Drop unused/obsolete "#config chip.h". - Use u8/u16/etc. everywhere. - Use pnp_read_config()/pnp_write_config() instead of open-coding them. - Use pnp_set_logical_device() instead of open-coding it. - W83627EHG: Fix incorrect enable_hwm_smbus() code comment. - Use ARRAY_SIZE. - w83627hf/superio.c: w83627hf_16_bit_addr_qual(): Bugfix, the code was using 'dev->path.pnp.port >> 8' as config port, which is incorrect in superio.c (which has a "real" device_t struct, in contrast to *_early_serial.c which uses "unsigned" as device_t where 'dev >> 8' is required).
