Subject: x86/platform/pcspeaker: Use PTR_ERR_OR_ZERO() to fix ptr_ret.cocci warning
X-Git-Tag: microblaze-v5.0-rc1~675^2~1
X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=2397134ce2d73dcf1d4846579f594c9f3880b2ec;p=linux-2.6-microblaze.git

x86/platform/pcspeaker: Use PTR_ERR_OR_ZERO() to fix ptr_ret.cocci warning

The ptr_ret.cocci script generates the following warning:

  arch/x86/kernel/pcspeaker.c:12:8-14: WARNING: PTR_ERR_OR_ZERO can be used

Use PTR_ERR_OR_ZERO() rather than an open-coded version to fix this.
