Andy Shevchenko 6bdec2b3a4 dmaengine: dw: disable BLOCK IRQs for non-cyclic xfer ... [ Upstream commit ee1cdcdae5 ] The commit 2895b2cad6 ("dmaengine: dw: fix cyclic transfer callbacks") re-enabled BLOCK interrupts with regard to make cyclic transfers work. However, this change becomes a regression for non-cyclic transfers as interrupt counters under stress test had been grown enormously (approximately per 4-5 bytes in the UART loop back test). Taking into consideration above enable BLOCK interrupts if and only if channel is programmed to perform cyclic transfer.
