[PATCH v1 20/26] ACPICA: Fix Segmentation Fault error related to DTPR
Posted by Rafael J. Wysocki 3 weeks, 4 days ago
From: Michal Camacho Romero <michal.camacho.romero@intel.com>

Fix Segmentation Fault error, caused by invalid buffer lenght in DTPR
Table Template:

 * Update buffer length for TPR Table, which invalid value caused
   Segmentation Fault, during ASL file production.

 * Refactor invalid values of TPR instances, arrays and serialization
   requests count and TPR Base addresses in the DTPR table template.

 * Fix offset updating in the acpi_dm_dump_dtpr function.
