Subject: omap_hdq: fix usecount handling
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7b46a105dbb7b67ea1f2f63a0b3ec29ab64e1bd3;p=openwrt%2Fstaging%2Fblogic.git

omap_hdq: fix usecount handling

hdq_usecount was set to zero after a successful read, so
omap_hdq_put could not properly free resources which leads
e.g. to increasing usecounts in lsmod output
