Subject: can: m_can_platform: remove unnecessary m_can_class_resume() call
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=0704c57436947c9f9f6472fd1a5ade41fc4c19d8;p=uclinux-h8%2Flinux.git

can: m_can_platform: remove unnecessary m_can_class_resume() call

The function m_can_runtime_resume() is getting recursively called from
m_can_class_resume(). This results in a lock up.

We need not call m_can_class_resume() during m_can_runtime_resume().
