Subject: drm/sun4i: dsi: delete unnecessary IS_ERR() checks
Git-commit: 37f67d390d160f4bf6bde76e5113acfc004ee96a
Patch-mainline: v5.19-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
The "dsi->bus_clk" pointer cannot be an error pointer at this point.
The check is confusing and unnecessary. Delete it.
