2024-12-02module: Convert symbol namespace to string literalPeter Zijlstra
Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.

2024-06-11hwmon: (pmbus/mp2856) Let enum chips start with index 0Guenter Roeck
Earlier it was assumed that the data pointer in of_device_id must not start with 0 (NULL) if i2c_get_match_data() is used. However, it turns out that this is perfectly fine as long as there is also an i2c_device_id array with the same data, which is used as fallback in that case. Let enum chips start with 0 to avoid confusion against other drivers where the enum starts with 0 and i2c_get_match_data() is used as well. While doing that, remove chip_id from struct mp2856_data since it is only used in the probe function, and typecast the result of i2c_get_match_data() to kernel_ulong_t to avoid the double typecast.
