#define __HAL_RCC_GPIOA_CLK_ENABLE() do { \ __IO uint32_t tmpreg = 0x00U; \ SET_BIT(RCC->AHB1ENR, RCC_AHB1ENR_GPIOAEN);\ \ tmpreg = READ_BIT(RCC->AHB1ENR, RCC_AHB1ENR_GPIOAEN);\ UNUSED(tmpreg); \ } while(0U)

Notes

After reset, the peripheral clock (used for registers read/write access) is disabled and the application software has to enable this clock before using it.
