[U-Boot] [PATCH] usb: Fix error handling in musb_hcd.c

[Marek Vasut]

Dear Andrew Murray,

> The wait_until_[rx|tx]ep_ready functions return a u8 to indicate success
> containing the value 0, 1 or -1. This patch changes the return type to an
> int to accommodate the negative return values.
> 
> These functions are used in the file using calls such as if (!wait_until...
> Where a -1 is returned it is mishandled and treated as success instead of
> a CRC error. This patch addresses this.
