linux-toradex.git/drivers/ata/pata_of_platform.c, branch v2.6.34.8 Linux kernel for Apalis and Colibri modules powerpc: Fix no interrupt handling in pata_of_platform 2008-10-10T04:55:17+00:00 Anton Vorontsov avorontsov@ru.mvista.com 2008-10-06T07:26:54+00:00 4538d0ca71b4f8991c4c0f433d7d17805738326e When no interrupt is specified the pata_of_platform fills the irq_res resource with -1, which is wrong to do for two reasons: 1. By definition, 'no irq' should be IRQ 0, not some negative integer; 2. pata_platform checks for irq_res.start > 0, but since irq_res.start is unsigned type, the check will be true for `-1'.

Also add || PPC to the PATA_PLATFORM's "depends on" Kconfig entry, needed for PA Semi Electra.
