Because mips uses #define with do..while(0) for outw_p (and not inline like other arches) herems.h fails to compile. ?: requires and expr and do..while(0) is a statement. Here are the compile errors followed by my proposed patches for both 2.4 and 2.6. build errors with CONFIG_HERMES=y hermes.h: In function `hermes_set_irqmask': hermes.h:337: parse error before "do" hermes.h:337: parse error before ';' token hermes.h: In function `hermes_write_words': 2.4 Index: drivers/net/wireless/hermes.h =================================================================== RCS file: /home/cvs/linux/drivers/net/wireless/hermes.h,v retrieving revision 1.6.2.4 diff -u -r1.6.2.4 hermes.h --- drivers/net/wireless/hermes.h 13 Aug 2003 17:19:20 -0000 1.6.2.4 +++ drivers/net/wireless/hermes.h 27 Aug 2003 21:37:24 -0000 @@ -302,12 +302,14 @@ #define hermes_read_reg(hw, off) ((hw)->io_space ? \ inw((hw)->iobase + ( (off) << (hw)->reg_spacing )) : \ readw((hw)->iobase + ( (off) << (hw)->reg_spacing ))) -#define hermes_write_reg(hw, off, val) ((hw)->io_space ? \ - outw_p((val), (hw)->iobase + ( (off) << (hw)->reg_spacing )) : \ - writew((val), (hw)->iobase + ( (off) << (hw)->reg_spacing ))) - -#define hermes_read_regn(hw, name) (hermes_read_reg((hw), HERMES_##name)) -#define hermes_write_regn(hw, name, val) (hermes_write_reg((hw), HERMES_##name, (val))) +#define hermes_write_reg(hw, off, val) do { \ + if ( (hw)->io_space ) \ + outw_p((val), (hw)->iobase + ( (off) << (hw)->reg_spacing )); \ + else \ + writew((val), (hw)->iobase + ( (off) << (hw)->reg_spacing )); \ + } while (0) +#define hermes_read_regn(hw, name) hermes_read_reg((hw), HERMES_##name) +#define hermes_write_regn(hw, name, val) hermes_write_reg((hw), HERMES_##name, (val)) /* Function prototypes */ void hermes_struct_init(hermes_t *hw, ulong address, int io_space, int reg_spacing); 2.6 Index: drivers/net/wireless/hermes.h =================================================================== RCS file: /home/cvs/linux/drivers/net/wireless/hermes.h,v retrieving revision 1.10 diff -u -r1.10 hermes.h --- drivers/net/wireless/hermes.h 22 Jun 2003 23:09:54 -0000 1.10 +++ drivers/net/wireless/hermes.h 27 Aug 2003 21:46:20 -0000 @@ -302,12 +302,14 @@ #define hermes_read_reg(hw, off) ((hw)->io_space ? \ inw((hw)->iobase + ( (off) << (hw)->reg_spacing )) : \ readw((hw)->iobase + ( (off) << (hw)->reg_spacing ))) -#define hermes_write_reg(hw, off, val) ((hw)->io_space ? \ - outw_p((val), (hw)->iobase + ( (off) << (hw)->reg_spacing )) : \ - writew((val), (hw)->iobase + ( (off) << (hw)->reg_spacing ))) - -#define hermes_read_regn(hw, name) (hermes_read_reg((hw), HERMES_##name)) -#define hermes_write_regn(hw, name, val) (hermes_write_reg((hw), HERMES_##name, (val))) +#define hermes_write_reg(hw, off, val) do { \ + if ( (hw)->io_space ) \ + outw_p((val), (hw)->iobase + ( (off) << (hw)->reg_spacing )); \ + else \ + writew((val), (hw)->iobase + ( (off) << (hw)->reg_spacing )); \ + } while (0) +#define hermes_read_regn(hw, name) hermes_read_reg((hw), HERMES_##name) +#define hermes_write_regn(hw, name, val) hermes_write_reg((hw), HERMES_##name, (val)) /* Function prototypes */ void hermes_struct_init(hermes_t *hw, ulong address, int io_space, int reg_spacing);
