seq_file is _the_ standard interface for simple text proc files. Though, we still need to support the binary proc files and the text file write, and also we need to manage the device disconnection gracefully. Thus this patch just replaces the text file read code with seq_file while keeping the rest intact. snd_iprintf() helper function is now a macro to expand itself to seq_printf() to be compatible with the existing code. The seq_file object is stored to the unused entry->rbuffer->buffer pointer. When the output size is expected to be large (greater than PAGE_SIZE), the driver should set entry->size field beforehand. Then the given size will be preallocated and the multiple show calls can be avoided. Acked-by: Jaroslav Kysela <perex@perex.cz> Signed-off-by: Takashi Iwai <tiwai@suse.de> |
