stm32l0xx_ll_spi.h causes compile warnings about aliasing. Solution for F0 works here as well. Tested on STM32L073RZ with 16-bit transfers. Signed-off-by: Ilya Tagunov <tagunil@gmail.com> |

STM32CubeL0
###########
Origin:
ST Microelectronics

Status:
version 1.10.0
Purpose:
ST Microelectronics official MCU package for STM32L0 series.
Description:
This package is an extract of official STM32CubeL0 package written by ST Microelectronics.
It is composed of STM32Cube hardware abstraction layer (HAL) and low layer (LL) plus a set
of CMSIS headers files, one for each SoC in STM32L0 series.
Dependencies:
None.

Patch List:
*Current implementation of LL_SPI_TransmitData16 on L0 family
generates following warning:
"warning: dereferencing type-punned pointer will break strict-aliasing
rules [-Wstrict-aliasing]"
Besides being forbidden by rule, this cast is not needed, as register is
16 bits wide. Modification has been tested on L0 SoC.
stm32yyxx_ll_spi.h being included in soc.h file, warning is generated
at each compiled object, this commit allows a clean build.
