The patch titled rtc: rtc-ds1374: fix 'no irq' case handling has been removed from the -mm tree. Its filename was rtc-rtc-ds1374-fix-no-irq-case-handling.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: rtc: rtc-ds1374: fix 'no irq' case handling From: Anton Vorontsov <avorontsov@xxxxxxxxxxxxx> On a PowerPC board with ds1374 RTC I'm getting this error while RTC tries to probe: rtc-ds1374 0-0068: unable to request IRQ This happens because I2C probing code (drivers/of/of_i2c.c) is specifying IRQ0 for 'no irq' case, which is correct. The driver handles this incorrectly, though. This patch fixes it.
