From e96fabd8791aad30a3c8a03919893ae3e2e3df25 Mon Sep 17 00:00:00 2001 From: Tobias Klauser Date: Wed, 9 Feb 2011 10:56:52 +0100 Subject: [PATCH] tty: serial: altera_uart: Handle pdev->id == -1 in altera_uart_remove Commit 6b5756f176568a710d008d3b478128fafb6707f0 introduced the possibility for pdev->id being -1 but the change was not done equally in altera_uart_remove. This patch fixes this.
