extcon: int3496: process id-pin first so that we start with the right status
commitpull/10/head0434352d3d
upstream. Some other drivers may be waiting for our extcon to show-up, exiting their probe methods with -EPROBE_DEFER until we show up. These drivers will typically get the cable state directly after getting the extcon, this commit changes the int3496 code to wait for the initial processing of the id-pin to complete before exiting probe() with 0, which will cause devices waiting on the defered probe to get reprobed. This fixes a race where the initial work might still be running while other drivers were already calling extcon_get_state(). Fixes:2f556bdb9f
