Bug#683329: flash-kernel: Toshiba AC100 support broken [fix included]

[Vincent Zweije <vincent@zweije.nl>]

Package: flash-kernel
Version: 3.2
Followup-For: Bug #683329

Dear Maintainer,

This is probably the same bug, although the original report contains
close to zero information...

Trying to flash a new kernel failed - flash-kernel exits early because
some shell command returned an error code. I have tracked this down to
faulty boot device detection.

This little loop from /usr/share/flash-kernel/functions around line 468
does the detection:

		for p in "$android_boot_device"*[0-9]; do
			abootimg="$(LC_ALL=C abootimg -i "$p" 2>/dev/null)"
			image_size="$(abootimg_get_image_size "$abootimg")"
			if [ -n "$image_size" ] &&
				[ "$image_size" -gt "$largest_size" ]; then
				part="$p"
			fi
		done

The assignment to abootimg contains a call to abootimg -i "$p". This
call fails when the glob pattern on the line above returns a block device
that is not an android boot image. Since the script is executed with -e,
this aborts the script.

Adding a "|| :" after the command fixes the problem thus:

		for p in "$android_boot_device"*[0-9]; do
			abootimg="$(LC_ALL=C abootimg -i "$p" 2>/dev/null || : )"
			image_size="$(abootimg_get_image_size "$abootimg")"
			if [ -n "$image_size" ] &&
				[ "$image_size" -gt "$largest_size" ]; then
				part="$p"
			fi
		done
