Series media: Use devm_of_reserved_mem_device_init() |

Commit Message

Mukesh Ojha Sept. 2, 2026, 8:07 p.m. UTC 
Switch to devm_of_reserved_mem_device_init() so the reserved memory
region is released automatically on probe failure or device removal.
Remove the four explicit of_reserved_mem_device_release() calls and
collapse the now-empty err_release_mem label into err_free.
