ALSA: pcm: remove structure member of 'struct snd_pcm_hwptr_log *' type because this structure had been removed
This structure was added by 4d96eb255c53 ('ALSA: pcm_lib - add possibility to log last 10 DMA ring buffer positions') to store PCM pointers information of latest 10 pointer movements (=XRUN_LOG_CNT). When CONFIG_SND_PCM_XRUN_DEBUG is configured, 'struct snd_pcm_runtime' has 'hwptr_log' member with a pointer to the structure. When calling xrun_log() in pcm_lib.c, the structure was allocated to the pointer. When calling snd_pcm_detach_substream() in pcm.c, the allocated pointer is released. In f5914908a5b7 ('ALSA: pcm: Replace PCM hwptr tracking with tracepoints'), the pointer logging is replaced with using Linux Kernel Tracepoints. The structure was also removed, while it's just declared. The member and kfree still remains. This commit removes the member and related codes. I think this was overlooked because it brings no errors/warnings to C compilers.
