From 846f98056a77f8587bd3fd08a219f8a95f5f2f27 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Petr=20=C5=A0tetiar?= Date: Tue, 19 Mar 2019 18:13:50 +0100 Subject: [PATCH] kernel: Backport ar933x_uart build fix (fixes FS#2152) MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Andrey has reported on OpenWrt's bug tracking system[1], that he currently can't use ar93xx_uart as pure serial UART without console (CONFIG_SERIAL_8250_CONSOLE and CONFIG_SERIAL_AR933X_CONSOLE undefined), because compilation ends with following error: ar933x_uart.c: In function 'ar933x_uart_console_write': ar933x_uart.c:550:14: error: 'struct uart_port' has no member named 'sysrq' 1. https://bugs.openwrt.org/index.php?do=details&task_id=2152 Signed-off-by: Petr Å tetiar --- ...rt-Fix-build-failure-with-disabled-c.patch | 99 +++++++++++++++++++ ...rt-Fix-build-failure-with-disabled-c.patch | 99 +++++++++++++++++++ 2 files changed, 198 insertions(+) create mode 100644 target/linux/generic/backport-4.14/060-v5.1-serial-ar933x_uart-Fix-build-failure-with-disabled-c.patch create mode 100644 target/linux/generic/backport-4.19/060-v5.1-serial-ar933x_uart-Fix-build-failure-with-disabled-c.patch diff --git a/target/linux/generic/backport-4.14/060-v5.1-serial-ar933x_uart-Fix-build-failure-with-disabled-c.patch b/target/linux/generic/backport-4.14/060-v5.1-serial-ar933x_uart-Fix-build-failure-with-disabled-c.patch new file mode 100644 index 0000000000..cb653170ef --- /dev/null +++ b/target/linux/generic/backport-4.14/060-v5.1-serial-ar933x_uart-Fix-build-failure-with-disabled-c.patch @@ -0,0 +1,99 @@ +From 72ff51d8dd262d1fef25baedc2ac35116435be47 Mon Sep 17 00:00:00 2001 +From: =?UTF-8?q?Petr=20=C5=A0tetiar?= +Date: Wed, 6 Mar 2019 17:54:03 +0100 +Subject: [PATCH] serial: ar933x_uart: Fix build failure with disabled console +MIME-Version: 1.0 +Content-Type: text/plain;
