Subject: Fix a const pointer usage warning in the Digigram VX soundcard driver
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b561c74ae2832d32cc189ecd82863d31151cdcb5;p=openwrt%2Fstaging%2Fblogic.git

Fix a const pointer usage warning in the Digigram VX soundcard driver

Fix a const pointer usage warning in the Digigram VX soundcard driver.  A
const pointer is being passed to copy_from_user() to load the firmware into.
This is okay in this case because the function has allocated the firmware
struct itself, but the const qualifier will be part of the firmware
struct - so the patch casts the const away.
