Signed-off-by: Geert Uytterhoeven --- Compile-tested only. Marked RFC, as this depends on [PATCH 01/17], but follows a different path to upstream. --- sound/pci/ice1712/wm8766.c | 14 +++++++------- sound/pci/ice1712/wm8776.c | 14 +++++++------- 2 files changed, 14 insertions(+), 14 deletions(-) diff --git a/sound/pci/ice1712/wm8766.c b/sound/pci/ice1712/wm8766.c index fe3e243b38549035..3e4d7f8f692785b0 100644 --- a/sound/pci/ice1712/wm8766.c +++ b/sound/pci/ice1712/wm8766.c @@ -7,6 +7,7 @@ * Copyright (c) 2012 Ondrej Zary */ +#include #include #include #include @@ -212,11 +213,10 @@ static int snd_wm8766_ctl_get(struct snd_kcontrol *kcontrol, if (wm->ctl[n].get) wm->ctl[n].get(wm, &val1, &val2); else { - val1 = wm->regs[wm->ctl[n].reg1] & wm->ctl[n].mask1; - val1 >>= __ffs(wm->ctl[n].mask1); + val1 = field_get(wm->ctl[n].mask1, wm->regs[wm->ctl[n].reg1]); if (wm->ctl[n].flags & WM8766_FLAG_STEREO) { - val2 = wm->regs[wm->ctl[n].reg2] & wm->ctl[n].mask2; - val2 >>= __ffs(wm->ctl[n].mask2); + val2 = field_get(wm->ctl[n].mask2, + wm->regs[wm->ctl[n].reg2]); if (wm->ctl[n].flags & WM8766_FLAG_VOL_UPDATE) val2 &= ~WM8766_VOL_UPDATE; } @@ -251,19 +251,19 @@ static int snd_wm8766_ctl_put(struct snd_kcontrol *kcontrol, wm->ctl[n].set(wm, regval1, regval2); else { val = wm->regs[wm->ctl[n].reg1] & ~wm->ctl[n].mask1; - val |= regval1 << __ffs(wm->ctl[n].mask1); + val |= field_prep(wm->ctl[n].mask1, regval1); /* both stereo controls in one register */ if (wm->ctl[n].flags & WM8766_FLAG_STEREO && wm->ctl[n].reg1 == wm->ctl[n].reg2) { val &= ~wm->ctl[n].mask2; - val |= regval2 << __ffs(wm->ctl[n].mask2); + val |= field_prep(wm->ctl[n].mask2, regval2); } snd_wm8766_write(wm, wm->ctl[n].reg1, val); /* stereo controls in different registers */ if (wm->ctl[n].flags & WM8766_FLAG_STEREO && wm->ctl[n].reg1 != wm->ctl[n].reg2) { val = wm->regs[wm->ctl[n].reg2] & ~wm->ctl[n].mask2; - val |= regval2 << __ffs(wm->ctl[n].mask2); + val |= field_prep(wm->ctl[n].mask2, regval2); if (wm->ctl[n].flags & WM8766_FLAG_VOL_UPDATE) val |= WM8766_VOL_UPDATE; snd_wm8766_write(wm, wm->ctl[n].reg2, val); diff --git a/sound/pci/ice1712/wm8776.c b/sound/pci/ice1712/wm8776.c index 6eda86119dff60b3..b4edf8a03c342351 100644 --- a/sound/pci/ice1712/wm8776.c +++ b/sound/pci/ice1712/wm8776.c @@ -7,6 +7,7 @@ * Copyright (c) 2012 Ondrej Zary */ +#include #include #include #include @@ -486,11 +487,10 @@ static int snd_wm8776_ctl_get(struct snd_kcontrol *kcontrol, if (wm->ctl[n].get) wm->ctl[n].get(wm, &val1, &val2); else { - val1 = wm->regs[wm->ctl[n].reg1] & wm->ctl[n].mask1; - val1 >>= __ffs(wm->ctl[n].mask1); + val1 = field_get(wm->ctl[n].mask1, wm->regs[wm->ctl[n].reg1]); if (wm->ctl[n].flags & WM8776_FLAG_STEREO) { - val2 = wm->regs[wm->ctl[n].reg2] & wm->ctl[n].mask2; - val2 >>= __ffs(wm->ctl[n].mask2); + val2 = field_get(wm->ctl[n].mask2, + wm->regs[wm->ctl[n].reg2]); if (wm->ctl[n].flags & WM8776_FLAG_VOL_UPDATE) val2 &= ~WM8776_VOL_UPDATE; } @@ -525,19 +525,19 @@ static int snd_wm8776_ctl_put(struct snd_kcontrol *kcontrol, wm->ctl[n].set(wm, regval1, regval2); else { val = wm->regs[wm->ctl[n].reg1] & ~wm->ctl[n].mask1; - val |= regval1 << __ffs(wm->ctl[n].mask1); + val |= field_prep(wm->ctl[n].mask1, regval1); /* both stereo controls in one register */ if (wm->ctl[n].flags & WM8776_FLAG_STEREO && wm->ctl[n].reg1 == wm->ctl[n].reg2) { val &= ~wm->ctl[n].mask2; - val |= regval2 << __ffs(wm->ctl[n].mask2); + val |= field_prep(wm->ctl[n].mask2, regval2); } snd_wm8776_write(wm, wm->ctl[n].reg1, val); /* stereo controls in different registers */ if (wm->ctl[n].flags & WM8776_FLAG_STEREO && wm->ctl[n].reg1 != wm->ctl[n].reg2) { val = wm->regs[wm->ctl[n].reg2] & ~wm->ctl[n].mask2; - val |= regval2 << __ffs(wm->ctl[n].mask2); + val |= field_prep(wm->ctl[n].mask2, regval2); if (wm->ctl[n].flags & WM8776_FLAG_VOL_UPDATE) val |= WM8776_VOL_UPDATE; snd_wm8776_write(wm, wm->ctl[n].reg2, val);
