Subject: ALSA: firewire-lib: fix inappropriate assignment between signed/unsigned type

From: Takashi Sakamoto <[email protected]>

commit dfb00a56935186171abb5280b3407c3f910011f1 upstream.

An abstraction of asynchronous transaction for transmission of MIDI messages was introduced in Linux v4.4. Each driver can utilize this abstraction to transfer MIDI messages via fixed-length payload of transaction to a certain unit address. Filling payload of the transaction is done by callback. In this callback, each driver can return negative error code, however current implementation assigns the return value to unsigned variable.

This commit changes type of the variable to fix the bug.
