Question about patch musb: use dma mode 1 for TX if transfer size equals maxpacket

Hi, folks

I have a question about patch d1043a2697effee3054451a9293a376bfb013e4b
musb: use dma mode 1 for TX if transfer size equals maxpacket.

Is this patch still needed on latest linux-next tree ?

And in its comment Anand said a better fix might be in musb_g_tx(),
Can someone give me some guides on how to do it ?

Since dma1 mode can't work on my blackfin platform, I want to change
it back to mode0 when transfer size equals maxpacket.

Thanks!
