[PATCH 09/10] misc: ti-st: remove ptr from recv functions

["Jiri Slaby (SUSE)" <jirislaby@kernel.org>]

ptr is the same as data, so use ptr directly as a parameter and drop the
useless local variable.

Likely, the two were introduced to have a different type. But 'char' and
'unsigned char' are the same in the kernel for a long time.
