misc: ti-st: Replace GFP_ATOMIC with GFP_KERNEL in kim_probe
kim_probe() is never called in atomic context. This function is only set as ".probe" in struct platform_driver. Despite never getting called from atomic context, kim_probe() calls kzalloc() with GFP_ATOMIC, which does not sleep for allocation. GFP_ATOMIC is not necessary and can be replaced with GFP_KERNEL, which can sleep and improve the possibility of sucessful allocation. This is found by a static analysis tool named DCNS written by myself. And I also manually check it.
