Subject: n_tty: Remove alias ptrs in __receive_buf()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8cb06c983822103da1cfe57b9901e60a00e61f67;p=linux-beck.git

n_tty: Remove alias ptrs in __receive_buf()

The char and flag buffer local alias pointers, p and f, are
unnecessary; remove them.
