Subject: [PATCH] iio: mma8452: fix probe fail when device tree compatible is used.
Git-commit: fe18894930a025617114aa8ca0adbf94d5bffe89
Patch-mainline: v5.19-rc4
References: git-fixes

Correct the logic for the probe. First check of_match_table, if
not meet, then check i2c_driver.id_table. If both not meet, then
return fail.
