+Subject: media: solo6x10: replace max(a, min(b, c)) by clamp(b, a, c)
+
+commit 31e97d7c9ae3de072d7b424b2cf706a03ec10720 upstream.
+
+This patch replaces max(a, min(b, c)) by clamp(b, a, c) in the solo6x10
+driver.  This improves the readability and more importantly, for the
+solo6x10-p2m.c file, this reduces on my system (x86-64, gcc 13):
+
+ - the preprocessed size from 121 MiB to 4.5 MiB;
+
+ - the build CPU time from 46.8 s to 1.6 s;
+
+ - the build memory from 2786 MiB to 98MiB.
+
+In fine, this allows this relatively simple C file to be built on a
+32-bit system.
