net: mvpp2: Return correct error codes
The return value of kzalloc on failure of allocation of memory should be -ENOMEM and not -1. Found using Coccinelle. A simplified version of the semantic patch used is: //<smpl> @@ expression *e; position p,q; @@ e@q = kzalloc(...); if@p (e == NULL) { ... return - -1 + -ENOMEM ; } //</smpl> This function may also return -1 after calling mpp2_prs_tcam_port_map_get. So that the function consistently returns meaningful error values on failure, the -1 is changed to -EINVAL. Signed-off-by: NAmitoj Kaur Chawla <amitoj1606@gmail.com> Signed-off-by: NDavid S.
