[PATCH v4] scripts: Makefile.lib: generate dsdt_generated.c instead of dsdt.c

Philippe Reynes philippe.reynes at softathome.com
Fri Feb 25 18:30:05 CET 2022 

There is a conflict between the static file
lib/acpi/dsdt.c and the file dsdt.c generated
dynamicaly by scripts/Makefile.lib. When a
mrproper is done, the static file dsdt.c is
removed. If a build with acpi enabled is
launched after, the following error is raised:

  CC      lib/acpi/acpi_table.o
make[2]: *** No rule to make target 'lib/acpi/dsdt.asl', needed by 'lib/acpi/dsdt.c'.  Stop.
scripts/Makefile.build:394: recipe for target 'lib/acpi' failed

To avoid such error, the generated file is named
dsdt_generated.c instead of dstdt.c.

Changelog:
v4:
- update dsdt.* to dsdt_generated.* in several .gitignore
v3:
- update comments in file scripts/Makefile.lib
- add changelog
v2
- change generated file name (dsdt_generated.c)
  instead of changing the name of the static file
- NOTE : forgot to call it v2 and forgot changelog
