H A D | mmci.c | f7ad7504 Sat Apr 16 17:45:49 CDT 2022 Linus Walleij <linus.walleij@linaro.org> mmc: mmci: Break IRQ status loop when all zero
We iterate an extra time through the IRQ status handling loop despite nothing had fired. Enabling the debug prints:
mmci-pl18x 80005000.mmc: op 01 arg 00000000 flags 000000e1 mmci-pl18x 80005000.mmc: irq0 (data+cmd) 00000001 mmci-pl18x 80005000.mmc: irq0 (data+cmd) 00000000 mmci-pl18x 80005000.mmc: op 01 arg 40ff8080 flags 000000e1 mmci-pl18x 80005000.mmc: irq0 (data+cmd) 00000001 mmci-pl18x 80005000.mmc: irq0 (data+cmd) 00000000
It is pointless to loop through the function when status is zero. Just break the loop if the status is zero.
