[PATCH v3 10/17] i3c: renesas: Return immediately if there is no transfer

[Claudiu Beznea <claudiu.beznea@kernel.org>]

From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>

There is no need to allocate a transfer structure when i2c_nxfers is zero.
Return immediately instead of unnecessarily allocating memory.
