The timeout test in axi_dma_init is not correct due to the
post-decrement used on the timeout variable which will mean timeout is
not 0 if the timeout occurs. Make the timeout variable an int instead of
a u32 and then test for timeout being -1.

In ks8851_mll_detect_chip the if..else code detects the case of (val &
0xfff0) != CIDER_ID and returns if found. So testing for this again will
always fail and the code is unreachable. Just remove the test and code
block.

In ca_phy_probe when checking for an external phy it uses a field from
the internal phy due to what is assumed to be a copy/paste typo. Make
the obvious fix to use the field from the external phy.

In rvu_af_init if the code fails to allocate memory for nix_af it will
take the error path with nix_af == NULL which will dereference nix_af.
Add the appropriate NULL check.

In nix_lf_setup there is a default value assigned to err in case an
error is detected. However this default value will be overwritten in the
for loop so that later code does not return an error code from the
function. Add a new assignment to restore err to the default error code.

In mvpp2_probe the code attempts to get a value for "gop-port-id" and
assigns it to port->gop_id but it then tests port->id for being equal to
-1. That is an impossible test as port->id is a field of type u8 so
cannot be negative. Change the test to port->gop_id.
