Subject: [PATCH 9/9] avutil/x86/asm: Remove wrong comment, rename FF_REG_sp
Before FFmpeg commit 531b0a316b24f00965cd8a88efdbea2c6d63147f,
FFmpeg used REG_SP as macro for the stack pointer, yet this
clashed with a REG_SP define in Solaris system headers, so it
was changed to REG_sp and a comment was added for this.
Libav fixed it by adding an FF_ prefix to the macros in
1e9c5bf4c136fe9e010cc8a7e7270bba0d1bf45e. FFmpeg switched
to using these prefixes in 9eb3da2f9942cf1b1148d242bccfc383f666feb6,
using FF_REG_sp instead of Libav's FF_REG_SP. In said commit
the comment was changed to claim that Solaris system headers
define FF_REG_SP, but this is (most likely) wrong.
This commit removes the wrong comment and renames the (actually unused)
macro to FF_REG_SP to make it consistent with FF_REG_BP.
