From bb2b4edaff3897233117ec7b1ee2bc67ed1e8187 Mon Sep 17 00:00:00 2001 From: Hanna Hawa Date: Mon, 19 Dec 2022 17:23:45 +0000 Subject: [PATCH] i2c: designware: fix i2c_dw_clk_rate() return size to be u32 [ Upstream commit f2e1fa99550dd7a882229e2c2cd9ecab4ce773d0 ] Make i2c_dw_clk_rate() to return u32 instead of unsigned long, as the function return the value of get_clk_rate_khz() which returns u32.
