-Subject: seq_file: Add a seq_bprintf function
-
-From: Florent Revest <revest@chromium.org>
-
-[ Upstream commit 76d6a13383b8e3ff20a9cf52aa9c3de39e485632 ]
-
-Similarly to seq_buf_bprintf in lib/seq_buf.c, this function writes a
-printf formatted string with arguments provided in a "binary
-representation" built by functions such as vbin_printf.
