The rework of the console infrastructure which aims to -support threaded and atomic consoles, requires to mark sections which -modify the UART registers as unsafe. This allows the atomic write function -to make informed decisions and eventually to restore operational state. It -also allows to prevent the regular UART code from modifying UART registers -while printk output is in progress. - -All modifications of UART registers are guarded by the UART port lock, -which provides an obvious synchronization point with the console -infrastructure. - -To avoid adding this functionality to all UART drivers, wrap the -spin_[un]lock*() invocations for uart_port::lock into helper functions -which just contain the spin_[un]lock*() invocations for now. In a -subsequent step these helpers will gain the console synchronization -mechanisms. - -Converted with coccinelle. No functional change. - -Signed-off-by: Thomas Gleixner -Signed-off-by: John Ogness -Link: https://lore.kernel.org/r/20230914183831.587273-69-john.ogness@linutronix.de -Signed-off-by: Greg Kroah-Hartman -Signed-off-by: Sebastian Andrzej Siewior ---- - drivers/tty/serial/sunsu.c | 46 ++++++++++++++++++++++----------------------- - 1 file changed, 23 insertions(+), 23 deletions(-) - ---- a/drivers/tty/serial/sunsu.c -+++ b/drivers/tty/serial/sunsu.c -@@ -212,9 +212,9 @@ static void enable_rsa(struct uart_sunsu - { - if (up->port.type == PORT_RSA) { - if (up->port.uartclk != SERIAL_RSA_BAUD_BASE * 16) { -- spin_lock_irq(&up->port.lock); -+ uart_port_lock_irq(&up->port); - __enable_rsa(up); -- spin_unlock_irq(&up->port.lock); -+ uart_port_unlock_irq(&up->port); - } - if (up->port.uartclk == SERIAL_RSA_BAUD_BASE * 16) - serial_outp(up, UART_RSA_FRR, 0); -@@ -234,7 +234,7 @@ static void disable_rsa(struct uart_suns - - if (up->port.type == PORT_RSA && - up->port.uartclk == SERIAL_RSA_BAUD_BASE * 16) { -- spin_lock_irq(&up->port.lock); -+ uart_port_lock_irq(&up->port); - - mode = serial_inp(up, UART_RSA_MSR); - result = !(mode & UART_RSA_MSR_FIFO); -@@ -247,7 +247,7 @@ static void disable_rsa(struct uart_suns - - if (result) - up->port.uartclk = SERIAL_RSA_BAUD_BASE_LO * 16; -- spin_unlock_irq(&up->port.lock); -+ uart_port_unlock_irq(&up->port); - } - } - #endif /* CONFIG_SERIAL_8250_RSA */ -@@ -311,10 +311,10 @@ static void sunsu_enable_ms(struct uart_ - container_of(port, struct uart_sunsu_port, port); - unsigned long flags; - -- spin_lock_irqsave(&up->port.lock, flags); -+ uart_port_lock_irqsave(&up->port, &flags); - up->ier |= UART_IER_MSI; - serial_out(up, UART_IER, up->ier); -- spin_unlock_irqrestore(&up->port.lock, flags); -+ uart_port_unlock_irqrestore(&up->port, flags); - } - - static void -@@ -456,7 +456,7 @@ static irqreturn_t sunsu_serial_interrup - unsigned long flags; - unsigned char status; - -- spin_lock_irqsave(&up->port.lock, flags); -+ uart_port_lock_irqsave(&up->port, &flags); - - do { - status = serial_inp(up, UART_LSR); -@@ -470,7 +470,7 @@ static irqreturn_t sunsu_serial_interrup - - } while (!(serial_in(up, UART_IIR) & UART_IIR_NO_INT)); - -- spin_unlock_irqrestore(&up->port.lock, flags); -+ uart_port_unlock_irqrestore(&up->port, flags); - - return IRQ_HANDLED; - } -@@ -545,9 +545,9 @@ static unsigned int sunsu_tx_empty(struc - unsigned long flags; - unsigned int ret; - -- spin_lock_irqsave(&up->port.lock, flags); -+ uart_port_lock_irqsave(&up->port, &flags); - ret = serial_in(up, UART_LSR) & UART_LSR_TEMT ?
