Missing 'LL_GPIO_PinState' typedef in STM32CubeL1 (v1.8.1) low-level drivers

[jfolsom]

There are two typedefs in the 'stm32l1xx_hal_gpio.h' file: 'GPIO_InitTypeDef' and 'GPIO_PinState'. The first has a corresponding entry in the low-level drivers (stm32l1xx_ll_gpio.h), but the other one is missing.

It looks like this in the HAL file:

/** 
  * @brief  GPIO Bit SET and Bit RESET enumeration 
  */
typedef enum
{
  GPIO_PIN_RESET = 0,
  GPIO_PIN_SET
} GPIO_PinState;

To remain consistent with the other code modules, you may wish to add the following block to 'stm32l1xx_ll_gpio.h':

/** 
  * @brief  LL GPIO Bit SET and Bit RESET enumeration 
  */
typedef enum
{
  LL_GPIO_PIN_RESET = 0,
  LL_GPIO_PIN_SET
} LL_GPIO_PinState;

Hi @jfolsom​ ,

The typedef GPIO_PinState isn't required in stm32l1xx_hal_gpio.c, so there is no need to declare it.
