I bet you've already considered the simpler form:
struct something *instance = mem_to_flex_dup(byte_array, count, GFP_KERNEL);
if (IS_ERR(instance))
return PTR_ERR(instance);Sadly, this doesn't work in any way because mem_to_flex_dup() needs to know at least the type, hence passing 'instance', which is simpler than passing 'struct something'. johannes
