Subject: serial: 8250_tegra: Fix an error handling path in tegra_uart_probe()
From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>
commit 134f49dec0b6aca3259cd8259de4c572048bd207 upstream.
If an error occurs after reset_control_deassert(), it must be re-asserted,
as already done in the .remove() function.
