From 2c1f81381eadc6dd3c288ec4477b2fe572cf86dc Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 29 Mar 2017 08:27:15 +0200 Subject: ALSA: hda - Avoid tricky macros The macros _snd_hdac_chip_read() and *_write() expand to different types (b,w,l) per their argument. They were thought to be used only internally for other snd_hdac_chip_*() macros, but in some situations we need to call these directly, and they are way too ugly. Instead of saving a few lines, we just write these macros explicitly with the types, so that they can be used in a saner way.
