Kernel memory was allocated using kmm_malloc() or kmm_zalloc() but freed with with the user-space allocator free(). In the FLAT build, this is bad style, but not harmful because there is only a single, heap and malloc() and kmm_malloc() map to the same function.
But that is not true in the case of the PROTECTED or KERNEL builds. In those cases, there are separate heaps. kmm_malloc() will allocate from the kernel heap. free() will attempt to free the kernel memory from the user heap and will cause an assertion (or other obscure failure if assertions are disabled).
nxsem_timedwait_uninterruptible() must return -ECANCELED if the thread is canceled:
include/nuttx/semaphore.h: Return if nxsem_wait() returns ECANCELED meaning that the thread waiting for the semaphore has been canceled.
sched/semaphore/sem_timedwait.c: Same change (the inline version is in semaphore.h, the non-inlined version is in sem_tickwait.c).
drivers/sensors/lps25h.c and drivers/wireless/bluetooth/bt_uart_bcm4343x.c: Make sure that the caller deals correctly with the -ECANCELED return value.
Refer to issue 619.
* Simplify EINTR/ECANCEL error handling
1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx
* Unify the void cast usage
1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro
