Interrupts from i2c controller are enabled while i2c bus is in the suspend mode (I2C_IE register doesn't equals to 0).
Starting from the OMAP chips with version2 registers scheme there are 2 registers (I2C_IRQENABLE_SET and I2C_IRQENABLE_CLR) to manage interrupts instead of the older OMAP chips old scheme which have only one register (I2C_IE). Now for enabling interrupts we must use I2C_IRQENABLE_SET register and for disabling interrupts we must use I2C_IRQENABLE_CLR register.
Next patch fixes it.
Patch is based on: git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git tag: v3.10-rc2
Verified on OMAP4430.
