Note that those drivers are barely maintained and might disappear in the futur

+Subject: When checking malloc for success, it helps to use == NULL, instead of
+ =
+
+Fixes gcc 5.3 compiler warning:
+s3_bios.c: In function 'find_bios_string':
+s3_bios.c:49:2: warning: suggest parentheses around assignment used as
+    truth value [-Wparentheses]
+  if (bios = NULL)
+    ^
+
+[Tested by compiling only, as I have no S3 hardware, but clearly no one
+ else has tested this code since commit c41a1188ce53 in 2009, as it would
+ be segfaulting if run.]
