mfd: cgbc-core: Cleanup signedness in cgbc_session_request()

2025-03-14T11:48:03Z

This doesn't affect how the code works because there are some implicit casts, but the "ret" variable is used to hold negative error codes so it should be type int. Declare it as "int" instead of "unsigned int". Signed-off-by: Dan Carpenter Link: https://lore.kernel.org/r/9e812dfa-e216-4e40-bbf0-d0b63b110bb0@stanley.mountain Signed-off-by: Lee Jones

mfd: pcf50633: Remove remaining PCF50633 support

2025-03-14T11:42:51Z

Remove the remaining parts of the 50633, the core, headers and glue. The pcf50633 was used as part of the OpenMoko devices but the support for its main chip was recently removed in: commit 61b7f8920b17 ("ARM: s3c: remove all s3c24xx support") See https://lore.kernel.org/all/Z8z236h4B5A6Ki3D@gallifrey/ Remove it.

mfd: qnap-mcu: Convert commas to semicolons in qnap_mcu_exec()

2025-03-14T10:55:15Z

Replace comma between expressions with semicolons. Using a ',' in place of a ';' can have unintended side effects. Although that is not the case here, it is seems best to use ';' unless ',' is intended. Found by inspection. No functional change intended. Compile tested only.
