Subject: Re: [PATCH v3 1/3] powerpc/512x: add LocalPlus Bus FIFO device driver

Hello, Timur, thanks a lot for your review.
I'll fix all the issues you pointed at and return with v4.

The only question I have: why calling dma_unmap_single() from within
a spinlock is a bad practice?

Best regards,
Alexander
