Sometime HAL_I2C_IsDeviceReady present in stm32l4xx_hal_i2c.c returns HAL_TIMEOUT

We are using I2C1 in STM32L486 and occasionally we are seeing timeout while calling HAL_I2C_IsDeviceReady,

this we are calling before call to HAL_I2C_Master_Transmit_IT

This is happening when USART0 is in use and data transfer is happening on that.

We are digging into it and in parallel posted here , so that if anyone faced these kind of issue might provide direction in which to look.
