[alsa-devel] [PATCH v3 00/27] kill devm_ioremap_nocache

[Yisheng Xie]

Hi all,

When I tried to use devm_ioremap function and review related code, I found
devm_ioremap and devm_ioremap_nocache is almost the same with each other,
except one use ioremap while the other use ioremap_nocache. While ioremap's
default function is ioremap_nocache, so devm_ioremap_nocache also have the
same function with devm_ioremap, which can just be killed to reduce the size
of devres.o(from 20304 bytes to 18992 bytes in my compile environment).

I have posted two versions, which use macro instead of function for
devm_ioremap_nocache[1] or devm_ioremap[2]. And Greg suggest me to kill
devm_ioremap_nocache for no need to keep a macro around for the duplicate
thing. So here comes v3 and please help to review.

Thanks so much!
