From f1ce25f292e7ef7a86e44ec4d30a7e179d3ddce0 Mon Sep 17 00:00:00 2001 From: Ian Abbott Date: Wed, 8 Mar 2017 16:03:01 +0000 Subject: [PATCH] USB: serial: ftdi_sio: allow other bases for "event_char" The 'store' function for the "event_char" device attribute currently expects a base 10 value. The value is composed of an enable bit in bit 8 and an 8-bit "event character" code in bits 7 to 0. It seems reasonable to allow hexadecimal and octal numbers to be written to the device attribute in addition to decimal. Make it so. Change the debug message to show the value in hexadecimal, rather than decimal.
