Guenter Roeck 7aeef1548a hwmon: (lm90) Fix error return value from detect function ... lm90_detect_nuvoton() is supposed to return NULL if it can not detect a chip, or a pointer to the chip name if it does. Under some circumstances it returns an error pointer instead. Some versions of gcc interpret an ERR_PTR as region of size 0 and generate an error message. In function ‘__fortify_strlen’, inlined from ‘strlcpy’ at ./include/linux/fortify-string.h:159:10, inlined from ‘lm90_detect’ at drivers/hwmon/lm90.c:2550:2: ./include/linux/fortify-string.h:50:33: error: ‘__builtin_strlen’ reading 1 or more bytes from a region of size 0 50 | #define __underlying_strlen __builtin_strlen | ^ ./include/linux/fortify-string.h:141:24: note: in expansion of macro ‘__underlying_strlen’ 141 | return __underlying_strlen(p); | ^~~~~~~~~~~~~~~~~~~ Returning NULL instead of ERR_PTR() fixes the problem.
