That cause some doc compile warning: lib/genalloc.c:649: warning: Function parameter or member 'start_addr' not described in 'gen_pool_first_fit' lib/genalloc.c:667: warning: Function parameter or member 'start_addr' not described in 'gen_pool_first_fit_align' lib/genalloc.c:694: warning: Function parameter or member 'start_addr' not described in 'gen_pool_fixed_alloc' lib/genalloc.c:729: warning: Function parameter or member 'start_addr' not described in 'gen_pool_first_fit_order_align' lib/genalloc.c:752: warning: Function parameter or member 'start_addr' not described in 'gen_pool_best_fit' This patch fix this by adding parameter descriptions.
