amba: check if on remove callback ...

Currently we get a null pointer dereference when booting linux on RPi
which use "uart-pl011" driver. This driver doesn't implement a remove
driver callback. This patch adds a check before calling the remove
callback if the driver which use the amba bus implement such
functionality.

usb: core: drop unnecessary le16_to_cpu() conversion ...

In drivers/usb/core/usb.c we already have le16_to_cpus() conversion
just after usb_get_descriptor():

    390     /* correct le values */
    391     le16_to_cpus(&dev->descriptor->bcdUSB);
    392     le16_to_cpus(&dev->descriptor->idVendor);
    393     le16_to_cpus(&dev->descriptor->idProduct);
    394     le16_to_cpus(&dev->descriptor->bcdDevice);

so no additional idVendor/idProduct descriptor fields
le16_to_cpu() conversion is needed after that.

On the big-endian machines extra le16_to_cpu() conversion
leads to wrong idVendor/idProduct USB device parameters values
(e.g. see devinfo <usb-device> output), and to a much more
serious problem: idVendor/idProduct-based USB device detection
does not work.

introduce strerrorp ...

putting an error pointer into strerror can be a bit confusing since
strerror takes a positive error code but PTR_ERR returns a negative
number, so we have to do strerror(-PTR_ERR(errp)). Some places got
this wrong already, so introduce a strerrorp function which directly
takes an error pointer.
