Subject: [ALSA] rme9652 - Fix the hw_pointer check
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=304e3bb7a15d839cef64b24a1bcc1230b2ae6fa6;p=openwrt%2Fstaging%2Fblogic.git

[ALSA] rme9652 - Fix the hw_pointer check

The negative check in hw_pointer callback doesn't work because the
value is unsigned.  Cast to int in the comparison to fix this.
