staging: kpc2000: kpc_dma: Convert set_page_dirty() --> set_page_dirty_lock()

Browse source

First, convert set_page_dirty() to set_page_dirty_lock()

Second, there is an interval in there after set_page_dirty() and
before put_page(), in which the device could be running and setting
pages dirty. Moving set_page_dirty_lock() after dma_unmap_sg().
