#     crypto: marvell/octeontx - fix double free of ptr
#     
#     Currently in the case where eq->src != req->ds, the allocation of
#     ptr is kfree'd at the end of the code block. However later on in
#     the case where enc is not null any of the error return paths that
#     return via the error handling return path end up performing an
#     erroneous second kfree of ptr.
#     
#     Fix this by adding an error exit label error_free and only jump to
#     this when ptr needs kfree'ing thus avoiding the double free issue.
#     
#     Addresses-Coverity: ("Double free")
#     Fixes: 10b4f09491bf ("crypto: marvell - add the Virtual Function driver for CPT")

WARNING: vmlinux.o(.text+0x2fc8): Section mismatch in reference from the variable start_here_common to the function .init.text:start_kernel()
The function start_here_common() references
the function __init start_kernel().
This is often because start_here_common lacks a __init 
annotation or the annotation of start_kernel is wrong.
