[PATCH v9 02/37] flash: prefix error codes with FL_

Jerome Forissier jerome.forissier at linaro.org
Fri Aug 23 15:48:06 CEST 2024


Prefix the flash status codes (ERR_*) with FL_ in order to avoid clashes
with third-party libraries. Case in point: including the lwIP library
header file <lwip/err.h> which defines err_enum_t as an enum with values
being ERR_*.
