From 0b60525b4e88b0ae656b89733f577a76d474f07a Mon Sep 17 00:00:00 2001 From: Alexander Sverdlin Date: Fri, 27 Nov 2020 11:19:53 +0100 Subject: [PATCH] tty: serial: uartlite: Support probe deferral Give uartlite a chance to be probed when IRQ controller will be finally available and return potential -EPROBE_DEFER as-is. The condition "<=" has been changed to "<" to follow the recommendation in the header of platform_get_irq().
