crypto: pcomp - Constify (de)compression parameters
In testmgr, struct pcomp_testvec takes a non-const 'params' field, which is pointed to a const deflate_comp_params or deflate_decomp_params object. With gcc-5 this incurs the following warnings: In file included from ../crypto/testmgr.c:44:0: ../crypto/testmgr.h:28736:13: warning: initialization discards 'const' qualifier from pointer target type [-Wdiscarded-array-qualifiers] .params = &deflate_comp_params, ^ ../crypto/testmgr.h:28748:13: warning: initialization discards 'const' qualifier from pointer target type [-Wdiscarded-array-qualifiers] .params = &deflate_comp_params, ^ ../crypto/testmgr.h:28776:13: warning: initialization discards 'const' qualifier from pointer target type [-Wdiscarded-array-qualifiers] .params = &deflate_decomp_params, ^ ../crypto/testmgr.h:28800:13: warning: initialization discards 'const' qualifier from pointer target type [-Wdiscarded-array-qualifiers] .params = &deflate_decomp_params, ^ Fix this by making the parameters pointer const and constifying the things that use it.
