 They match.  The one I downloaded from you:
 
 17024 / 0be34c61ce8d5c077d607fff205e6a13
 
 The one from kernel.org:
 
 17024 / 0be34c61ce8d5c077d607fff205e6a13
 
 The difference is that the one from kernel.org contains a bunch of
 lower-case files such as:
 
 -rw-r--r--  1 rcb  users    8832 Jan 22 11:26 kaveri_ce.bin
 -rw-r--r--  1 rcb  users    8832 Jan 22 11:26 kaveri_me.bin
 -rw-r--r--  1 rcb  users   17024 Jan 22 11:26 kaveri_mec.bin
 -rw-r--r--  1 rcb  users   17024 Jan 22 11:26 kaveri_mec2.bin
 -rw-r--r--  1 rcb  users    8832 Jan 22 11:26 kaveri_pfp.bin
 -rw-r--r--  1 rcb  users   10496 Jan 22 11:26 kaveri_rlc.bin
 -rw-r--r--  1 rcb  users    4456 Jan 22 11:26 kaveri_sdma.bin
 -rw-r--r--  1 rcb  users    4456 Jan 22 11:26 kaveri_sdma1.bin
 -rw-r--r--  1 rcb  users  232752 Jan 22 11:26 kaveri_uvd.bin
 -rw-r--r--  1 rcb  users  101072 Jan 22 11:26 kaveri_vce.bin
 
 and upper case files:
 
 -rw-r--r--  1 rcb  users    8576 Jan 22 11:26 KAVERI_ce.bin
 -rw-r--r--  1 rcb  users    8576 Jan 22 11:26 KAVERI_me.bin
 -rw-r--r--  1 rcb  users   16768 Jan 22 11:26 KAVERI_mec.bin
 -rw-r--r--  1 rcb  users    8576 Jan 22 11:26 KAVERI_pfp.bin
 -rw-r--r--  1 rcb  users   10240 Jan 22 11:26 KAVERI_rlc.bin
 -rw-r--r--  1 rcb  users    4200 Jan 22 11:26 KAVERI_sdma.bin
 
 whereas the original only has the upper-case files (with the exception
 of the one you had me try.)
