FORCE_INLINE_ATTR TYPE& operator>>=(TYPE& a, int b) { a >>= b; return a; } \

It seems the intention was to use the >> and << operators defined a couple of lines above (like in the |= etc operators). But this version currently just results in infinite recursion.

@0xjakob
v4.4 needs the same fix.
v4.3 needs backport fix:
$ git grep "FORCE_INLINE_ATTR TYPE& operator>>="
components/riscv/include/esp_attr.h:FORCE_INLINE_ATTR TYPE& operator>>=(TYPE& a, int b) { a >>= b; return a; }
components/spi_flash/sim/stubs/xtensa/esp_attr.h:FORCE_INLINE_ATTR TYPE& operator>>=(TYPE& a, int b) { a >>= b; return a; }
components/xtensa/include/esp_attr.h:FORCE_INLINE_ATTR TYPE& operator>>=(TYPE& a, int b) { a >>= b; return a; } \

@AxelLin Sorry, the backports slipped through, we're creating them now.
