Heinrich Schuchardt	c11f0d88ba	coccinelle: adjust NULL check before free() ... The free() function checks if its argument is NULL. We should avoid checking for NULL before calling free like in     if (result->tds)         free(result->tds); The list of relevant functions differs between Linux and U-Boot, e.g. we use free(). Adjust the list of relevant functions. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>	2020-04-24 16:40:09 -04:00
