Subject: coresight: Fix freeing up the coresight connections
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=1b015ef28a443a89985db2a67080bf7c660d66d2;p=openwrt%2Fstaging%2Fblogic.git

coresight: Fix freeing up the coresight connections

With commit c2c729415b2d2132 ("coresight: platform: Cleanup coresight
connection handling"), we switched to re-using coresight_connections
for the coresight_device. However, that introduced a mismatch in the
alloc/free of the connections. The allocation is made using devm_*,
while we use kfree() to release the memory when a device is released
(even though we don't support this at the moment). Fix this by leaving
it to the automatic freeing of the memory.
