This reverts commit 2a63e34. This needs to be reverted as otherwise the type of ssize_t will be "unsigned long" which is not correct. (gdb) ptype ssize_t type = unsigned long For example this check would fail in that case ssize_t foo(void) { return -1; } ... if (foo() < 0) { printk("This is never called\n"); } Fixes zephyrproject-rtos#17378 Signed-off-by: Jukka Rissanen <jukka.rissanen@linux.intel.com>
