2022-05-05fsl_lpuart: Don't enable interrupts too earlyIndan Zupancic
If an irq is pending when devm_request_irq() is called, the irq handler will cause a NULL pointer access because initialisation is not done yet.

2022-05-05tty: n_gsm: fix invalid gsmtty_write_room() resultDaniel Starke
gsmtty_write() does not prevent the user to use the full fifo size of 4096 bytes as allocated in gsm_dlci_alloc(). However, gsmtty_write_room() tries to limit the return value by 'TX_SIZE' and returns a negative value if the fifo has more than 'TX_SIZE' bytes stored. This is obviously wrong as 'TX_SIZE' is defined as 512. Define 'TX_SIZE' to the fifo size and use it accordingly for allocation to keep the current behavior. Return the correct remaining size of the fifo in gsmtty_write_room() via kfifo_avail().

2022-05-05tty: n_gsm: fix mux activation issues in gsm_config()Daniel Starke
The current implementation activates the mux if it was restarted and opens the control channel if the mux was previously closed and we are now acting as initiator instead of responder, which is the default setting. This has two issues. 1) No mux is activated if we keep all default values and only switch to initiator. The control channel is not allocated but will be opened next which results in a NULL pointer dereference. 2) Switching the configuration after it was once configured while keeping the initiator value the same will not reopen the control channel if it was closed due to parameter incompatibilities. The mux remains dead. Fix 1) by always activating the mux if it is dead after configuration. Fix 2) by always opening the control channel after mux activation.

2022-05-05tty: n_gsm: fix buffer over-read in gsm_dlci_data()Daniel Starke
'len' is decreased after each octet that has its EA bit set to 0, which means that the value is encoded with additional octets. However, the final octet does not decreases 'len' which results in 'len' being one byte too long. A buffer over-read may occur in tty_insert_flip_string() as it tries to read one byte more than the passed content size of 'data'. Decrease 'len' also for the final octet which has the EA bit set to 1 to write the correct number of bytes from the internal receive buffer to the virtual tty.

2022-05-05serial: 8250_mtk: Fix UART_EFR register addressAngeloGioacchino Del Regno
On MediaTek SoCs, the UART IP is 16550A compatible, but there are some specific quirks: we are declaring a register shift of 2, but this is only valid for the majority of the registers, as there are some that are out of the standard layout. Specifically, this driver is using definitions from serial_reg.h, where we have a UART_EFR register defined as 2: this results in a 0x8 offset, but there we have the FCR register instead. The right offset for the EFR register on MediaTek UART is at 0x98, so, following the decimal definition convention in serial_reg.h and accounting for the register left shift of two, add and use the correct register address for this IP, defined as decimal 38, so that the final calculation results in (0x26 << 2) = 0x98.

2022-05-05tty/serial: digicolor: fix possible null-ptr-deref in digicolor_uart_probe()Yang Yingliang
It will cause null-ptr-deref when using 'res', if platform_get_resource() returns NULL, so move using 'res' after devm_ioremap_resource() that will check it to avoid null-ptr-deref.
