pcm_hw_close: avoid SIGSEGV when pcm_hw_open fail
Prevent the call to pcm->ops-close() if pcm->ops->open() fail. Fix memory leak in pcm_hw_open() in case of failure. * thread #1, name = 'ut', stop reason = signal SIGSEGV: invalid address (fault address: 0x8) frame #0: 0x00007ffff7f863e8 libtinyalsa.so.1`pcm_hw_close(data=0x0000000000000000) at pcm_hw.c:61:21 58 { 59 struct pcm_hw_data *hw_data = data; 60 -> 61 if (hw_data->fd > 0) 62 close(hw_data->fd); 63 64 free(hw_data); (lldb) bt * thread #1, name = 'ut', stop reason = signal SIGSEGV: invalid address (fault address: 0x8) * frame #0: 0x00007ffff7f863e8 libtinyalsa.so.1`pcm_hw_close(data=0x0000000000000000) at pcm_hw.c:61:21 frame #1: 0x00007ffff7f8491c libtinyalsa.so.1`pcm_close(pcm=0x0000000000a9eba0) at pcm.c:820:5 frame #2: 0x00007ffff7f84e0a libtinyalsa.so.1`pcm_open(card=128, device=0, flags=13, config=0x00007fffffffd000) at pcm.c:957:5 Signed-off-by: Miguel GAIO <mgaio35@gmail.com>
