ALSA: core - strip too long file names in snd_print*()
When modules are built with M= option, they pass long file paths to __FILE__. This results in ugly outputs of snd_print*() when CONFIG_SND_VERBOSE_PRINTK is set. This patch adds a check of the path and strips the leading path dirs if the file name is an absolute path to improve the readability of logs. Signed-off-by: Takashi Iwai <tiwai@suse.de>
