video: bfin_adv7393fb: Convert to kstrtouint_from_user
This patch removes a call to the deprecated simple_strtoul function and simplifies the code by replacing two function calls with one call to kstrtouint_from_user. -Simplify the adv7393_write_proc function by replacing the simple_strtoul and copy_from_user calls with one call to kstrtouint_from_user. -Change the count parameter from unsigned long to size_t as this is the type that the kstrtouint_from_user function expects. (size_t is what will be passed to the adv7393_write_proc function by the proc write handler function proc_file_write anyway) Signed-off-by: Emil Goode <emilgoode@gmail.com> Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
