Description

When compiling the latest master I get the following warning message:

In file included from C:/Users/username/.platformio/packages/framework-arduinoespressif32/cores/esp32/esp32-hal.h:80,
                 from C:/Users/username/.platformio/packages/framework-arduinoespressif32/cores/esp32/esp32-hal-uart.c:15:
C:/Users/username/.platformio/packages/framework-arduinoespressif32/cores/esp32/esp32-hal-uart.c: In function 'uartBegin':
C:/Users/username/.platformio/packages/framework-arduinoespressif32/cores/esp32/esp32-hal-uart.c:460:51: warning: null pointer dereference [-Wnull-dereference]
         log_e("UART%d initialization error.", uart->num);

Due to the fact that I am using PlatformIO-Arduino 6.7.0 the line numbers are slightly different to the current master. The location in the current master is here:

arduino-esp32/cores/esp32/esp32-hal-uart.c

Lines 540 to 541 in 4db2edd

	uart = NULL;
	log_e("UART%d initialization error.", uart->num);
