commit 5de4db8fcb6d6fc7d9064c22841211790c0ab81b upstream.
We don't need to send firmware data asynchronously, much simpler is just use synchronous usb_bulk_msg().
[ stable note: this patch was originally developed as cleanup, but it remove incorrect usage of page_frag_alloc(): alloc more than PAGE_SIZE and create not ARCH_DMA_MINALIGN dma buffers needed at least for performance reason. Was tested on 5.0 and 4.20, see https://bugzilla.kernel.org/show_bug.cgi?id=202673 and https://bugzilla.kernel.org/show_bug.cgi?id=202241 ]

4.20 is now end-of-life, but I have queued this up for 5.0.y, thanks!
