Subject: drivers: base: remove check for callback in coredump_store()
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=1fe56e0cafd7e4cf26f3582aad0c7705fceff498;p=openwrt%2Fstaging%2Fblogic.git

drivers: base: remove check for callback in coredump_store()

The check for the .coredump() callback in coredump_store() is
redundant. It is already assured the device driver implements
the callback upon creating the coredump sysfs entry.
