media: cec: ch7322: drop of_match_ptr for ID table

2023-07-14T10:31:12Z

The driver can match only via the DT table so the table should be always used and the of_match_ptr does not have any sense (this also allows ACPI matching via PRP0001, even though it might not be relevant here). drivers/media/cec/i2c/ch7322.c:583:34: error: ‘ch7322_of_match’ defined but not used [-Werror=unused-const-variable=] Signed-off-by: Krzysztof Kozlowski Reviewed-by: Hans Verkuil Reviewed-by: Guenter Roeck Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: cec: i2c: ch7322: also select REGMAP

Selecting only REGMAP_I2C can leave REGMAP unset, causing build errors, so also select REGMAP to prevent the build errors. ../drivers/media/cec/i2c/ch7322.c:158:21: error: variable 'ch7322_regmap' has initializer but incomplete type 158 | static const struct regmap_config ch7322_regmap = { ../drivers/media/cec/i2c/ch7322.c:159:10: error: 'const struct regmap_config' has no member named 'reg_bits' 159 | .reg_bits = 8, ../drivers/media/cec/i2c/ch7322.c:159:21: warning: excess elements in struct initializer 159 | .reg_bits = 8, ../drivers/media/cec/i2c/ch7322.c:160:10: error: 'const struct regmap_config' has no member named 'val_bits' 160 | .val_bits = 8, ../drivers/media/cec/i2c/ch7322.c:160:21: warning: excess elements in struct initializer 160 | .val_bits = 8, ../drivers/media/cec/i2c/ch7322.c:161:10: error: 'const struct regmap_config' has no member named 'max_register' 161 | .max_register = 0x7f, ../drivers/media/cec/i2c/ch7322.c:161:25: warning: excess elements in struct initializer 161 | .max_register = 0x7f, ../drivers/media/cec/i2c/ch7322.c:162:10: error: 'const struct regmap_config' has no member named 'disable_locking' 162 | .disable_locking = true, ../drivers/media/cec/i2c/ch7322.c:162:28: warning: excess elements in struct initializer 162 | .disable_locking = true, ../drivers/media/cec/i2c/ch7322.c: In function 'ch7322_probe': ../drivers/media/cec/i2c/ch7322.c:468:26: error: implicit declaration of function 'devm_regmap_init_i2c' [-Werror=implicit-function-declaration] 468 | ch7322->regmap = devm_regmap_init_i2c(client, &ch7322_regmap); ../drivers/media/cec/i2c/ch7322.c:468:24: warning: assignment to 'struct regmap *' from 'int' makes pointer from integer without a cast [-Wint-conversion] 468 | ch7322->regmap = devm_regmap_init_i2c(client, &ch7322_regmap); ../drivers/media/cec/i2c/ch7322.c: At top level: ../drivers/media/cec/i2c/ch7322.c:158:35: error: storage size of 'ch7322_regmap' isn't known 158 | static const struct regmap_config ch7322_regmap = { Link: https://lore.kernel.org/linux-media/20230608025435.29249-1-rdunlap@infradead.org Fixes: 21b9a47e0ec7 ("media: cec: i2c: ch7322: Add ch7322 CEC controller driver") Signed-off-by: Randy Dunlap Cc: Jeff Chase Cc: Hans Verkuil Cc: Joe Tessler Cc: Arnd Bergmann Cc: Mark Brown Cc: Masahiro Yamada Signed-off-by: Mauro Carvalho Chehab

media: Switch i2c drivers back to use .probe()

2023-05-25T14:21:21Z

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then commit 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

i2c: Make remove callback return void

2022-08-16T10:46:26Z

The value returned by an i2c driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.
