From 6c18a43e3c82b0b67531a1cdec7ba31540fe6424 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Thu, 8 Aug 2019 20:02:04 -0700 Subject: scsi: qla2xxx: Enable type checking for the SRB free and done callback functions Since all pointers passed to the srb_t.done() and srb_t.free() functions have type srb_t, change the type of the first argument of these functions from void * into struct srb *. This allows the compiler to verify the argument types for these functions. This patch does not change any functionality.
