Drop the variables but keep the call to aty_ld_le32() as it may have unexpected side-effects. v2: - Updated subject (Lee) Signed-off-by: Sam Ravnborg Acked-by: Thomas Zimmermann Cc: Lee Jones Link: https://patchwork.freedesktop.org/patch/msgid/20201128224114.1033617-7-sam@ravnborg.org --- diff --git a/drivers/video/fbdev/aty/mach64_ct.c b/drivers/video/fbdev/aty/mach64_ct.c index f87cc81f4fa2b..011b07e44e0df 100644 --- a/drivers/video/fbdev/aty/mach64_ct.c +++ b/drivers/video/fbdev/aty/mach64_ct.c @@ -281,10 +281,13 @@ static u32 aty_pll_to_var_ct(const struct fb_info *info, const union aty_pll *pl void aty_set_pll_ct(const struct fb_info *info, const union aty_pll *pll) { struct atyfb_par *par = (struct atyfb_par *) info->par; - u32 crtc_gen_cntl, lcd_gen_cntrl; + u32 crtc_gen_cntl; u8 tmp, tmp2; - lcd_gen_cntrl = 0; +#ifdef CONFIG_FB_ATY_GENERIC_LCD + u32 lcd_gen_cntrl = 0; +#endif + #ifdef DEBUG printk("atyfb(%s): about to program:\n" "pll_ext_cntl=0x%02x pll_gen_cntl=0x%02x pll_vclk_cntl=0x%02x\n", @@ -402,7 +405,7 @@ static int aty_init_pll_ct(const struct fb_info *info, union aty_pll *pll) struct atyfb_par *par = (struct atyfb_par *) info->par; u8 mpost_div, xpost_div, sclk_post_div_real; u32 q, memcntl, trp; - u32 dsp_config, dsp_on_off, vga_dsp_config, vga_dsp_on_off; + u32 dsp_config; #ifdef DEBUG int pllmclk, pllsclk; #endif @@ -488,9 +491,9 @@ static int aty_init_pll_ct(const struct fb_info *info, union aty_pll *pll) /* Allow BIOS to override */ dsp_config = aty_ld_le32(DSP_CONFIG, par); - dsp_on_off = aty_ld_le32(DSP_ON_OFF, par); - vga_dsp_config = aty_ld_le32(VGA_DSP_CONFIG, par); - vga_dsp_on_off = aty_ld_le32(VGA_DSP_ON_OFF, par); + aty_ld_le32(DSP_ON_OFF, par); + aty_ld_le32(VGA_DSP_CONFIG, par); + aty_ld_le32(VGA_DSP_ON_OFF, par); if (dsp_config) pll->ct.dsp_loop_latency = (dsp_config & DSP_LOOP_LATENCY) >> 16;
