2023-04-13phy: intel: remove MODULE_LICENSE in non-modulesNick Alcock1-1/+0
Since commit 8b41fc4454e ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations are used to identify modules. As a consequence, uses of the macro in non-modules will cause modprobe to misidentify their containing object file as a module when it is not (false positives), and modprobe might succeed rather than failing with a suitable error message. So remove it in the files in this commit, none of which can be built as modules.

2023-03-20phy: intel: phy-intel-lgm-combo: Convert to platform remove callback ↵Uwe Kleine-König1-3/+2
returning void The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

In the probe path, dev_err() can be replaced with dev_err_probe() which will check if error code is -EPROBE_DEFER and prints the error name. It also sets the defer probe reason which can be checked later through debugfs.

Since the EMMC clock was changed from 200Mhz to 175Mhz in FIP, there were some warnings introduced, as the frequency values being checked was still wrt 200Mhz in code. Hence, the frequency checks are now updated based on the current 175Mhz EMMC clock changed in FIP.
