staging: most: core: rename aim variables
This patch replaces the 'aim' substrings of variable names with 'comp'. It is needed because of the renaming of AIM modules to components. Signed-off-by: Christian Gromm <christian.gromm@microchip.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
