lvgl 9.2.1 breaks develop branch

[twiesenthal]

Hi,

i'm fairly new to esp32 programming and using esp32-smartdisplay in general, so i don't feel confident enough to provide a fox for this in a merge request.
But i would like to let you know that with the merge from this issue, which was included in lvgl 9.2.1 yesterday, the develop branch is currently broken

sw_rotate was removed which results in build time errors like this.

esp32_smartdisplay/src/esp32_smartdisplay.c:197:15: error: 
'lv_display_t' {aka 'struct lv_display_t'} has no member named 'sw_rotate'

The simple solution is of course to pin the lvgl version to 9.2.0 in library.json, but that does not seem sustainable to me. Maybe someone more confident with the code can fix the root cause of the error.

Same error

Just committed fix for rotation. https://github.com/rzeldent/esp32-smartdisplay/tree/lvgl9.2

Does this work for you?

[bobskigit]

it works for me

[rzeldent]

Retested on software rotation device esp32-4848S040CIY1. Worked as expected.

PR to have this in the develop branch.
#210

Thank you very much @rzeldent. Works like a charm
