Hi all, I will resend this series as some mailbox issue happened with patch#3 and covering letter. Sorry for the issue. Cheers, Biju > Subject: [PATCH v5 0/4] Extend device_get_match_data() to struct > bus_type > > This patch series extend device_get_match_data() to struct bus_type, so > that buses like I2C can get matched data. > > v4->v5: > * Added const struct device_driver variable 'drv' in > i2c_device_get_match > _data(). > * For code readability and maintenance perspective, added separate NULL > check for drv and client variable and added comment for NULL check > for > drv variable. > * Created separate patch for converting i2c_of_match_device_sysfs() to > non-static. > * Removed export symbol for i2c_of_match_device_sysfs(). > * Replaced 'dev->driver'->'drv'. > * Replaced return value data->NULL to avoid (potentially) stale > pointers, > if there is no match. > > v3->v4: > * Documented corner case for device_get_match_data() > * Dropped struct i2c_driver parameter from i2c_get_match_data_helper() > * Split I2C sysfs handling in separate patch(patch#3) > * Added space after of_device_id for i2c_of_match_device_sysfs() > * Added const parameter for struct i2c_client, to prevent overriding > it's > pointer. > * Moved declaration from public i2c.h->i2c-core.h > v2->v3: > * Added Rb tag from Andy for patch#1. > * Extended to support i2c_of_match_device() as suggested by Andy. > * Changed i2c_of_match_device_sysfs() as non-static function as it is > needed for i2c_device_get_match_data(). > * Added a TODO comment to use i2c_verify_client() when it accepts const > pointer. > * Added multiple returns to make code path for device_get_match_data() > faster in i2c_get_match_data(). > RFC v1->v2: > * Replaced "Signed-off-by"->"Suggested-by" tag for Dmitry. > * Documented device_get_match_data(). > * Added multiple returns to make code path for generic fwnode-based > lookup faster. > * Fixed build warnings reported by kernel test robot <lkp@xxxxxxxxx> > * Added const qualifier to return type and parameter struct i2c_driver > in i2c_get_match_data_helper(). > * Added const qualifier to struct i2c_driver in i2c_get_match_data() > * Dropped driver variable from i2c_device_get_match_data() > * Replaced to_i2c_client with logic for assigning verify_client as it > returns non const pointer. > > Biju Das (4): > drivers: fwnode: Extend device_get_match_data() to struct bus_type > i2c: Add i2c_device_get_match_data() callback > i2c: i2c-core-of: Convert i2c_of_match_device_sysfs() to non-static > i2c: Extend i2c_device_get_match_data() to support i2c sysfs > > drivers/base/property.c | 27 ++++++++++++++++- > drivers/i2c/i2c-core-base.c | 60 ++++++++++++++++++++++++++++++------- > drivers/i2c/i2c-core-of.c | 4 +-- > drivers/i2c/i2c-core.h | 9 ++++++ > include/linux/device/bus.h | 3 ++ > 5 files changed, 90 insertions(+), 13 deletions(-) > > -- > 2.25.1
