Subject: [Buildroot] kernel patch not applied
Message-ID: <46432A7D.6050808@rcn.com>

I have a custom kernel patch I want applied when building the 2.6 kernel.  I
created a device under target/devices with a directory kernel-patches and
BR2_BOARD_PATH set correctly.  However, the patch is never applied apparently
because all patches are assumed to be minor kernel version patches.

In the case when DOWNLOAD_LINUX26_VERSION equals LINUX26_VERSION no patches,
including custom kernel patches, are applied. My current fix below will change
the directory name if minor kernel patches are applied, but still allow patches
in $(BR2_BOARD_PATH)/kernel-patches to be applied.

Could this cause problem elsewhere in the build?
