video: da8xx-fb rev2: fix disabling of palette completion interrupt
Writing '1' to particular bit of IRQENABLE_CLEAR register disables the corresponding interrupt on revision 2 LCDC. This register was wrongly configured to disable all previous enabled interrupts instead of disabling only palette completion interrupt. Patch fixes it by clearing only palette completion interrupt bit. Signed-off-by: Manjunathappa, Prakash <prakash.pm@ti.com> Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
