Hi,

attached is a patch which fixes following wanings:

drivers/ide/ide-tape.c: In function `idetape_setup':
drivers/ide/ide-tape.c:4701: Warnung: duplicate `const'
drivers/video/matrox/matroxfb_g450.c: In function `g450_compute_bwlevel':
drivers/video/matrox/matroxfb_g450.c:129: Warnung: duplicate `const'
drivers/video/matrox/matroxfb_g450.c:130: Warnung: duplicate `const'
drivers/video/matrox/matroxfb_maven.c: In function `maven_compute_bwlevel':
drivers/video/matrox/matroxfb_maven.c:347: Warnung: duplicate `const'
drivers/video/matrox/matroxfb_maven.c:348: Warnung: duplicate `const'

This is done by removing the 'const' from the temporary variables of the min() 
and max() macros. For me it seems to have no negative impact, so please 
consider applying...

Best regards
   Thomas Schlichter
