From dcf5ffc91c91cf58c5f172e83daa34d5ea6b69fc Mon Sep 17 00:00:00 2001 From: Daniel Lezcano Date: Sun, 14 Mar 2021 12:13:29 +0100 Subject: thermal/drivers/core: Use a char pointer for the cooling device name [ Upstream commit 58483761810087e5ffdf36e84ac1bf26df909097 ] We want to have any kind of name for the cooling devices as we do no longer want to rely on auto-numbering. Let's replace the cooling device's fixed array by a char pointer to be allocated dynamically when registering the cooling device, so we don't limit the length of the name. Rework the error path at the same time as we have to rollback the allocations in case of error. Tested with a dummy device having the name: "Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch" A village on the island of Anglesey (Wales), known to have the longest name in Europe.
