* iio:light:vcnl4035: Improve error reporting for problems during .remove()Uwe Kleine-König2022-06-111-2/+8
| | | | | | | | | | | | | | | | | Returning an error value in an i2c remove callback results in a generic error message being emitted by the i2c core, but otherwise it doesn't make a difference. The device goes away anyhow and the devm cleanups are called. So instead of triggering the generic i2c error message, emit a more helpful message if a problem occurs and return 0 to suppress the generic message. This patch is a preparation for making i2c remove callbacks return void.

As mc3230_set_opcon() already emits an error message on failure and the additional error message by the i2c core doesn't add any useful information, change the return value to zero to suppress this message. This patch is a preparation for making i2c remove callbacks return void.

While it's not freed back to system correctly when kdump kernel is reloaded or unloaded. Then memory leak is caused. Fix it by introducing x86 specific function arch_kimage_file_post_load_cleanup(), and freeing the buffer there. And also remove the incorrect elf header buffer freeing code. Before calling arch specific kexec_file loading function, the image instance has been initialized. So 'image->elf_headers' must be NULL. It doesn't make sense to free the elf header buffer in the place. Three different people have reported three bugs about the memory leak on x86_64 inside Redhat.
